I mentioned this in an older post, but thought I'd start a new one so I could get more feedback. I've been breastfeeding my 2 year old (she turned two in July). I started getting my period last March. My luteal phase was too short to get pregnant, but I tried taking progesterone (emerita brand, I put some on a cotton ball and wipe it on my skin before bed) to lengthen my luteal phase. In July it didn't help, but in August, I got pregnant. I started bleeding when I thought I was 10 weeks along, and an ultrasound confirmed that I had a miscarriage (the baby was only 4 or 6 weeks in size, but I was sure about the conception date). My doctor told me that my progesterone level was too low (she measured it when I started bleeding) and that I better stop breastfeeding for 3 months before trying to get pregnant again, or my kids will be very far spaced apart in age. She also measured that my thyroid was low. I will go to a different doctor to a get a second opinion (do I need to wean? When can I try to get pregnant again? Can I try in a few weeks when I stop bleeding and ovulate? Do I need to take progesterone? Do I need to take thyroid medicine? Do i need to wait 3 months before trying to get pregnant? I don't want to wait because I am 32 and my husband is older and may have a low sperm count). Would love advice. thank you!! Right now I think that breastfeeding caused my miscarriage because it made me have too low of a progesterone level. but I read that this is just an old wives tale!
