The doctor put me on provera today. Said everything looked great but since I had a miscarriage last year they would rather be safe and give me provera to help the babies develop until the placenta is fully attached to my uterine wall at 12 weeks. Is this common practice with Twin pregnancies. I couldn't find anything as far as side effects for the babies. I just read it may make me moody (already am) and sleepy (also already very sleepy) I am willing to do what ever the doctor says to make sure I have a successful pregnancy I was just wondering what other twin moms expierences were.
