I am 24 yrs old and I had sex on 12/3 /2017 ,had an ipill and got bleeding on14/3 though my periods were due on the 27 th of March. After that had only protected sex but on 5/4/2017 my boyfriend penetrated me without a condom for a brief moment and then we used condom.i still had an Ipill the same day. I started with a course of primolut n on 7/4till 11/4 but still haven't got my periods (18/4) .I am experiencing slight cramping in my lower abdomen and pain in my legs like when I have during PMS and periods but no periods.i took a
pregnancy test on 20/4 and it came out negative. What should I do?
