It's been awhile since I've been on here, so here's a little background:
-d&c at 9 weeks about 5 mos ago
-took 7.5 weeks for hcg to drop completely
-haven't been ovulating since loss
-got pregnant 3x (two children and 1 loss) very easily
My OB put me on 50mg clomid last cycle, and day 21 progesterone test showed I didn't ovulate. Now waiting for AF so we can try 100mg.
My question is, how many cycles should we try with the OB before we move on to an RE?? I don't understand how we were so fertile before, and now are not

.
Re: How many rounds of clomid?
I'm sorry you are having trouble now. Bodies are weird and they get weirder as we age. Hopefully you get your rainbow baby soon, but I would urge you to seek out an RE sooner rather than later.
The only monitoring we're doing with the OB is day 21 progesterone check and pelvic exam.
Also, my understanding is it can be fairly normal to have wonky cycles for a while after a loss. I don't know how old you are and don't want to minimize what you're going through, but if it took almost 2 months for your HCG to drop and your d&c was 5 months ago, so it sounds like you've been TTC for 3 months and aren't having normal cycles. I am not sure that is entirely out of the range of what might be expected.

If you use the search function on the TTGP board, you'll get lots of threads about Clomid use. Look for responses by @TheBorg7of9... She has lots of good info on why Clomid from an OB isn't a good route.
