Thank you.
I've done some more Googling and asking around and I'm going to see if my OB will add a progesterone check to my blood work for Monday. I could be totally wrong since I'm not a doctor but from my understanding this is what happened...
After you ovulate, the corpus luteum cyst forms and produces progesterone to help the fertilized egg implant and maintains it until the placenta takes over. If you don't conceive then the cyst "dies off" and your period starts. But if you're pregnant and have low progesterone, obviously nothing is adequately maintaining the pregnancy and you'll miscarry. I have the (now painful) cyst, I had a pregnancy, I had a miscarriage so it fits. Obviously the miscarriage could be unrelated to a low progesterone level but it fits. It makes sense. Last night I googled "symptoms of low progesterone" and it made sense. Heavy AF, insomnia (I have trouble sleeping like you wouldn't believe), fatigue (always so fatigued but always blamed it on low iron levels), vaginal dryness, bloating.
I know that there are still pregnancies that will miscarry regardless, that aren't related to this but if a supplement is all it would take to prevent more miscarriages, sign me up! I just hope my OB is open to my asking her to check it instead of just trusting her to figure it all out on her own haha. Without telling my Mom what happened (I'm not ready for her to know I was pregnant or even TTC) I asked about her progesterone supplement and she said she takes a topical cream she got online without a prescription. She said she loves it and that it's bio-identical and better than anything synthetic & that prescription pills from the doc are going to be synthetic and don't work as well. Obviously she's not a doctor so I don't know how true that is but it has me paranoid that if my progesterone is low, if the doc prescribes supplements, are they going to work as well as some online cream would or not? Ugh... too much to worry/think about.
