My doctor prescribed me Norethindrone because I am breast feeding my 2month old daughter. Well, I have been taking the pill for only 18days but I have taken it AT THE SAME TIME EVERYDAY (11:55-11:57AM) But me&my boyfriend had unprotected sex last night & I know for sure he went inside me. I'm just scared because I just had my first child & we're nor my body is ready. Hopefully someone will have advice.
