Has anyone here been taking progesterone for most of your pregnancy? Did your side effects from the progesterone change throughout the pregnancy? And how did you feel being on it? I’m experiencing a tightness of my stomach at 20 weeks and I’m not sure if it’s related to the use of progesterone or not.. (currently on 400mgx2 daily) I was experiencing cramps from the progesterone in the beginning but they sort of went away after a few weeks so not sure if they came back at this point.
