Hi! I have been on prometrium for about 5 months now. I have spotting between peroids due to low progesterone levels. I have some dizziness especially when i started to take it ( pill form, twice a day ) and most of the spotting has stopped except for a little bit of brown spotting after i ovulate. I know that a lot of women take it to help with implantation, especially after having a miscarriage. It is a promissing suppliment to take

Good luck
