Progesterone

I've never been so concerned about hormones. I have to take a progesterone supplement during the LP phase, which is the last 14 days of the cycle. I wonder if the HSG showed a thin uterine lining, because the progesterone is to thicken that. So, that's the plan this cycle. Some people have to take it until 11-12 weeks into the pregnancy because that's when the placenta takes over and produces it. I guess I'm getting too far ahead of myself, considering that I haven't even gotten a positive OPK yet. Hopefully that will happen tomorrow or Wednesday.
