What Are The Uses And Side Effects Of Primolut N?

I have been advised to take primolut N by the gynec to make sure the ovulation period will be correct for my intercourse with my husband when he arrives on vacation from abroad. later stage even after stopping the pills, my periods did not happen even after 14 days. I checked with the same doctor and she confirmed me pregnant and asked to come after 10 days. They showed me the heartbeat of my baby and told that baby is 100% healthy. Still I have a fear of having 10 tablets (twice a day for 5 days). I have different responses to my doubts.

Can you help me ?
