Hi Guys

I hope some of you recognize me!! It's been a while since I've been on this thread. But I do stalk from time to time! Hope everyone is doing well!!!
I had my rainbow baby a year ago thanks to this thread!! I Was d/x with MTHFR homo A type- had a successful pregnancy thanks to clomid, high dose folic acid, and oral progesterone.
Which leads to now, I am still nursing but my period has not yet returned- which can be normal (avg is 14 months). However, I am REALLY thin- I've always been naturally thin and I think nursing just kind of sucks the life out of me. I am 105lbs (normal around 118) at 5'4 so my BMI is less than 19%. My doctor did not like this and wanted to run some routine blood work.
Everything is okay except one indicator of a poor diet and malnutrition (which I'm going to work on) but she also tested some hormone levels... and I am really upset.
My FSH was 8.6 mIU. My estrogen was very low at 28.1 (typical with breastfeeding) so this number should be accurate. From what I read it is technically still considered a "good" FSH but for my age (I am 29) very bad and is an indicator of poor ovarian reserve and even low quality eggs.
To think I was hoping I could have another rainbow baby without the help of fertility doctors - I was finally not feeling any pressure to TTC and wanted to just let nature takes it course this time. Well this little number has made all optimism go out the window-and am right back to doubting if I'll be able to concieve. When I was going through fertility treatments for the M/C's two years ago - my ovarian reserve was never brought up and I'm sure they tested it. How can things change so much in two years? From what I've read nursing has no effect on the FSH number, but I'm hoping because I'm underweight at the moment and still in lactational amenorrhea that it could have something to do with it
Anyway- I was just wondering if any of you gals had any input. I am really not ready to wean - was hoping to go another year- but now I am terrified that I am racing against the clock for baby #2 which I very much want. To think I was feeling so zen about the whole thing- the pressure was off, and I'm honestly not ready for #2 yet. I wish I didn't know about this number.
