I'm Sarah. And I need to tell you something I've never said out loud.
For two years, I was terrified of having sex with my own husband.
Not because I didn't want to. But because I knew what was coming after.
The smell. The discharge. The itching. The trip to the doctor who would hand me the same metronidazole prescription she'd already given me eleven times. The yeast infection that would follow the antibiotics like clockwork. And then — two weeks later — the whole thing starting over again.
BV. Antibiotics. Yeast infection. Diflucan. Repeat.
I started sleeping on the far side of the bed. Making excuses. Wearing cotton granny panties instead of the cute ones I used to wear. Carrying boric acid suppositories in my purse like it was just a normal thing a woman does.
And I was disappearing from my own relationship. My husband couldn't understand why I kept pulling away. I couldn't explain it without crying. The shame of feeling broken in the most intimate part of yourself — while your partner is right there, wanting you — is a specific kind of lonely that no one talks about.
"I hadn't felt normal down there in so long, I couldn't even remember what normal felt like anymore."
And the worst part? I had no idea my IUD was doing this to me.
I Got the IUD Because It Was Supposed to Set Me Free
I got my copper IUD because I was done with hormones messing with my body. No daily pills. No mood swings. No pregnancy scares. Just set it and forget it for ten years.
For the first six months, it was everything I'd hoped for. I felt like myself again.
Then the infections started.
At first I thought it was a fluke. One round of antibiotics and it was gone. But two weeks later it was back. Then again. Then again. I started tracking it in my Notes app like a crime scene. January 4th. February 19th. March 3rd.
I went to three different doctors. All three told me the same thing:
"It's not your IUD."
- "It's not your IUD" — but it started the week after insertion
- "Just use the antibiotics" — but they stopped working after round 5
- "Try better hygiene" — I was showering twice a day in organic everything
- "Maybe it's stress" — it was not stress
- "Consider removing it" — but that wasn't an option I was willing to accept
And honestly? Even the idea of removing it terrified me. The IUD was the one thing that had finally worked as birth control. What if I took it out and went back to hormones that wrecked my mood? What if nothing else worked as well? I was trapped — too sick to keep it, too scared to lose it.
I was livid. I'd done everything right. Cotton underwear only. Unscented everything. No douching. No tight pants. I'd cut out sugar. I'd cut out alcohol. I ate plain yogurt every single day for a month. Nothing. Worked.
I spent over $2,000 on medications, OTC creams, specialty probiotics, boric acid by the case, and two visits to a vulvodynia specialist who charged $400 out of pocket just to tell me my vagina looked "irritated."
"I felt like I was being punished for choosing the birth control that finally worked for me."
Then I Found the Answer My Doctor Never Gave Me
Late one night — probably 1am, rabbit-holing through r/CopperIUD for the fourth time that week — I found a thread that changed everything.
A woman had posted about a study she'd found. It wasn't about bacteria. It wasn't about pH. It was about something called a biofilm.
How bacteria form a protective "fortress" on IUD strings — and why antibiotics can't reach them.
Here's what the research showed — and why no prescription had ever fixed me:
When you have an IUD, the strings that hang down through your cervix become a scaffold for bacteria. The bad bacteria — the ones that cause BV — form a protective layer around those strings called a biofilm. It's essentially a fortress.
Here's why that matters: antibiotics cannot penetrate that biofilm. They kill the bacteria floating freely in your vagina, which is why you feel better for two weeks. But the colony living on the strings? Untouched. The moment you stop taking antibiotics, they re-seed your entire vaginal environment.
This is why it always comes back.
And there was a second piece to the puzzle. The copper in a copper IUD specifically depletes Lactobacillus crispatus — the single most important strain of good bacteria in your vaginal microbiome. It's the bacteria your vagina needs to stay acidic, balanced, and infection-resistant.
Your IUD is literally killing the one thing protecting you.
(This applies to hormonal IUD users too — Mirena, Kyleena, Liletta. While copper has the strongest documented link, the biofilm mechanism is the same: the strings are the scaffold regardless of which IUD you have.)
"I hadn't done anything wrong. My body wasn't broken. My IUD was depleting the exact bacteria I needed, and nobody had ever told me."
Why Everything I'd Tried Before Was the Wrong Tool
Once I understood the biofilm problem, the failure of every solution I'd tried suddenly made complete sense.
Antibiotics: Kill surface bacteria. Cannot penetrate the biofilm on IUD strings. The colony reseeds within 2 weeks. This is not a failure of willpower. This is basic microbiology.
Boric acid: Amazing for fast symptom relief. Changes vaginal pH quickly. But it has zero biofilm-penetrating ability and zero ability to restore the Lactobacillus strains your IUD has depleted. The moment you stop using it, you're back where you started.
Generic "women's probiotics": The ones with Lactobacillus acidophilus on the label? Studies have consistently shown acidophilus has among the worst results for vaginal BV. It's a gut strain, not a vaginal strain. You've essentially been taking the wrong bacteria.
The problem wasn't that probiotics don't work. The problem was nobody had ever built one specifically for IUD users — with the right strains, the right biofilm-targeting ingredients, and the right understanding of what's actually happening in your body.
Meet the Solution Built for This
After months of research, I came across Morra — a vaginal probiotic built specifically around the IUD-microbiome connection. Not a generic women's health formula with pretty packaging. Something actually designed for this problem.
What made it different from everything I'd tried before:
- L. crispatus — The specific strain copper IUDs deplete. The gold standard for vaginal microbiome dominance. Most probiotics don't include it at all.
- L. rhamnosus + L. reuteri — The only two oral probiotic strains clinically proven to survive stomach acid and actually reach the vaginal tract. Studied in over 40 clinical trials.
- Bacteriophage complex (LH01, T4D, LL12, LL5) — This is the part nobody else has. Bacteriophages specifically target and break down the bacterial biofilm on IUD strings. Phages get through it.
- Biotin — Supports vaginal mucosal tissue and has specific anti-Candida properties. This is why yeast infections follow BV so reliably.
- 20 Billion CFU — Clinically relevant dose. Not the 1-5 billion you find in grocery store probiotics.
Morra's full ingredient panel — every strain, every reason.
I ordered the 3-month supply because I'd read enough to know that oral probiotics take 6–8 weeks to establish meaningful colonization. I wasn't going to quit at week 3. This time I was going all in.
What Happened Over the Next 8 Weeks
Weeks 1–2: Honestly, not much. A little less discharge than usual. I told myself to be patient.
Weeks 3–4: No new infection. I'd usually have had at least one by now. Cautiously optimistic.
Weeks 5–6: We had sex. Multiple times. I waited for the familiar flare. It didn't come.
Week 8: I cried in the bathroom. Happy crying. The kind you do when something you've been bracing for just... doesn't happen.
"For the first time in two years, I woke up and my first thought wasn't about my vagina. That sounds small. It was everything."
It's been six months now. I haven't had a single BV infection. I haven't taken antibiotics once. My IUD is still in. I kept my birth control. And I got my life back.
I Wasn't the Only One
When I started talking about this, other women reached out. Turns out I wasn't alone — not even close.
I've had my Paragard for 3 years and the BV started within the first month. I've been on 9 rounds of antibiotics and my doctor literally just kept prescribing the same thing. After two months on Morra I went from getting it every 3 weeks to not at all. I'm crying writing this. This is the first time in years I feel like myself again.
I was genuinely about to have my Mirena removed. I'd had it for 4 years and the last 2 were constant infections. My relationship was suffering, I was avoiding intimacy, I felt disgusting. I'm now 3 months into Morra and I've had one very mild episode that cleared on its own without antibiotics. I kept my IUD. I cannot believe this is real.
My husband and I weren't having sex for months. Because every time we did, I'd be back at the doctor within a week. Three months on this and we're actually intimate again. I feel like a woman again, not just a patient. The relationship angle alone is worth every penny.
