About 3 days ago I finally became negative on the urine beta HCG tests. Having gotten this green flag, I finally went in for my antral follicle count today.
And...phew. AFC is 15 follicles per ovary(!!!). Ovaries look polycystic but thankfully, ovarian volume looked normal. Most reassuringly, this definitely does not correlate with low ovarian reserve, which was my one gigantic fear since I found AMH was low. I also gave blood to retest for AMH and (for good measure), Vitamin D3 since I've been on massive doses of the latter for the past two weeks. Testing in India is cheap so I go nuts. Off topic, but I'm also getting Vitamin B12 tested (nothing to do with fertility that I know of), but Vitamin B12 deficiency is really common in the Indian population and has also cropped up in my family. Interestingly, severe deficiency of this vitamin seems to cause some mental issues (periods of rage, stress etc).
So, overall, it looks like I might have ovulatory PCOS (which according to my Indian RE may be compromising egg quality) but the jury is still out of the diagnosis. I'd be glad to have a confirmation, at least we would have something to treat.
