Rate of follicle growth on Clomid

Mega - October 19

Hi! I had an u/s on Monday to determine the size of my follicles and the results were rather disappointing. My biggest one was still quite a bit under 10 mm. I was on Clomid 100 mgs last week, finishing up on Friday. Because my cycle was off to a screwey start anyway b/c of a cyst, my RE didn't start me off on Clomid til cd 6 or so. So I thought with that head start, I'd grow some nice big follies. Anyway, I have a follow up u/s tomorrow, to further monitor growth. We're going on vacation next week & I really wanted to IUI this
weekend. Anyway, what I'm wondering is given the info above, what are my chances of my follie growing to 16 mm or so in 3 days? I guess I just want to hear stories (good & bad) about similar situations. And does anyone know how long it typically takes to stimulate the follies with Clomid? Also, just for more backstory, I have PCOS & am also on Metformin. Sorry for the "novel!" TIA!

Hi Mega, I started last month on clomid days 2-6 and shots day 7-10. my day 10 ultrasound showed 4 follicles on the right 24mm, and 3 at 15mm and then 1 smaller. by the next day they were at 29, 26 or 24 and 2 at 20mm. They made me trigger on this day and did my iui's the next 2 mornings. I dont think i ovulated til the morning of the 2nd iui. Hope ive helped some.

Thanks Isa! That's great that you had such nice sized follies, and since they grew so fast in one day, you have given me hope that maybe tomorrow's u/s will bring better news. Hopefully I'll have similiar luck.

Thanks! I'm sorry you didn't get a BFP with those really big follies. Good luck with this cycle. Hopefully this will be your lucky month!

Good luck to you Mega!. my doc says follicles may grow about 2mm a day. but mine seemed to be slow. they grow only 1 mm a day even after my 150mg clomid. that was quite disappointing. but i get my surge a few days later than the predicted day.

Thanks Annette. How frustrating that your follies grew so slowly, but at least you did get your surge. That's what counts. Good luck!

Good luck Gigi! There are several reasons drs prescribe Clomid, annovulation (like me), short leutal phase (LP), to produce a better quality of egg, etc...Clomid is often a first step fertility drug, it sounds like you're what they call unexplained infertility, and Clomid is used a lot in cases like yours. Typically with great success. Keep us posted on your first round of Clomid. Babydust!
