I am 2 months pregnant and I had a spotting found.. My doc has suggested for taking progesterone tablet and also took an Anti D injection. I have suggested to have this for 1 month. We did scan after 2 weeks after the spotting and the baby looks fine. We would like to know is it safe to have this tablet and how long should we tale this? And will this medicine cause hair fall? Is there any other thing which we should be cautious about?
