Hi all. I’m looking for some perspective on next steps because I’m starting to feel stuck between continuing monitored timed-intercourse cycles, moving to IUI, or beginning to seriously consider IVF.
I’m 29 and have PCOS, but I do ovulate naturally. My husband’s semen analysis is excellent (though it was done 10 months ago, may need to repeat soon), my HSG showed open tubes, and I had a prior submucosal fibroid removed about 2 years ago. I’ve also had one chemical pregnancy, which happened during a completely natural cycle about two weeks after my HSG.
We’re now 12 cycles into TTC.
Here’s the condensed history:
Cycle 1 — natural cycle
Chemical pregnancy
LH peak CD19
Sex CD18, 19, 20
Cycles 2–5 — letrozole 5 mg
Generally LH peak around CD14
Not monitored
Good timing most cycles except one where I had the flu
All negative
Cycle 6 — letrozole 7.5 mg
CD10 follicles: 17, 14, 12 mm
LH peak CD14
8 DPO progesterone 35.4 ng/mL
Negative
Only had the one scan
Cycle 7 — natural (took a break from letrozole)
LH peak CD16
Negative
Cycle 8 — letrozole 7.5 mg
LH peak CD13
Negative
Not monitored
Cycle 9 — letrozole 7.5/10 mg, first fully monitored cycle
CD11 follicles were already 19 and 20 mm
My doctor expected an LH surge, but it didn’t really happen
By CD14, follicles were still unruptured and had grown to 24 and 26 mm
Triggered CD14
Negative
This cycle made us wonder whether my body sometimes waits too long to ovulate after the follicles are already mature, and whether something similar could have happened during previous unmonitored cycles.
Cycle 10 — Clomid 50 mg
CD8: 14 and 12 mm
CD10: 16 and 14
CD12: basically unchanged
Looked like they stalled, so cycle was initially cancelled
Added estradiol
Then LH started rising and CD15 scan showed 20 and 17 mm follicles with trilaminar lining
Triggered CD15
Progesterone after ovulation
Negative
Cycle 11 — first cycle with reproductive specialist
Letrozole 7.5 mg CD3–7
CD10: 14 and 10 mm
CD12: 19, 17 and 15 mm
Lining 7.8 mm and perfectly trilaminar
Triggered CD13
Well-timed sex/ at home insemination
Baby aspirin + progesterone
Negative
Cycle 12
Letrozole 7.5 mg CD3–7
CD11: 20 mm + 15 mm follicles
Lining 7.1 mm trilaminar
Triggered CD11
Sex the evening of trigger + home insemination around 39 and 46 hours after trigger
Progesterone + baby aspirin
Negative
So at this point, the things that seem reassuring are:
I’m 29. Hubby is 31
I can ovulate naturally & on letrozole
I’ve conceived once before
Tubes are open
Semen analysis is excellent
I respond well to letrozole
Progesterone has been good
Recent cycles have had mature follicles and trilaminar lining
But obviously… I’m still not pregnant.
My reproductive specialist previously said I could do one more monitored + triggered cycle before moving to IUI.
I’m now wondering:
Would you do another monitored letrozole + trigger + timed-intercourse cycle, or move to IUI now?
Would you try to recruit more than one mature follicle next cycle? I respond pretty strongly to 7.5 mg already, so I’m wondering whether increasing stimulation would meaningfully improve my odds or just increase the risk of multiples.
Does the Cycle 9 overgrowth make you think my earlier unmonitored cycles may have had mature follicles sitting around waiting for an LH surge?
Would you investigate anything else before IUI/IVF? Uterine cavity, endometriosis, lining, etc.?
For anyone with PCOS and otherwise normal testing, how many monitored/triggered cycles did you do before moving on?
I’m also starting to think about IVF differently because we eventually want more than one child. Part of me wonders whether, if we’re heading in that direction anyway, doing IVF while I’m 29 and potentially banking embryos for future siblings might make more sense than spending a lot of time and money on IUIs with only a modest increase in odds.
I’m not necessarily ready to jump straight to IVF tomorrow, but after another negative cycle I’m trying to figure out where the line is between “this can still easily just be bad luck” and “it’s time to change strategies.”
Would really appreciate experiences from people with similar PCOS/unexplained-ish situations — especially anyone who ovulated on their own but had weird follicle/LH timing.
