prometrium/progesterone supplement side effects??!!

I had two consecutive miscarriages within the year, found out couple weeks ago I'm pregnant again. Went in today for ultrasound, I'm 6w4d. Everything seems good so far 🎉 dr put me on progesterone/prometrium to be on the safe side. His office is closed now and I took it and I'm feeling super funky and weird 😳 like space cadet. Is this normal or anyone experience this?
