Low progesterone

So I went and had my OB panel a couple of days ago. Like in my first pregnancy, my progesterone was low. First pregnancy it was a 7 and today it was a 7.6. I got injections in my thighs for today and a prescription for a vaginal suppository starting tomorrow. They also want me on oral, but I’m allergic to gelatin so they have to make the capsules special so in the meantime tbh have me using a progesterone cream from a local health food store. While I know that everything was fine with my daughter, I’m still worried. I don’t think anyone expect me not to be. They did an ultrasound and I’m very early, but he was able to confirm a corpus luteum, a thickened uterus, and something in my uterus. The corpus luteum gave me a lot of hope. I’m also waiting on a second HCG screen to see how the levels are moving, but with it going into the weekend I’m afraid I may not hear anything till next week and I’m really anxious until I know things are getting better. Reassurance/comments/success stories?
