I am facing periods irregularities, I had unprotected sex on 31st December and I took ipill the next day itself and it had no side effects as such my periods also came on time date was 12 January after that I had no sexual intercourse and since that day my periods are not coming it's March 4 today I had a bit of spotting I used tampon and I had no idea about whats happening. Once I took out the tampon there was no blood so I am concerned what is wrong with my periods, is it work pressure or some other problem I am not able to understand.
