Hi. My period comes on every 26 or 27 of a month. I had an ipill on 18th sept followed by withdrawal bleeding on 24th sept. It lasted for 3 days. But now it is 27th oct and yet i am not having my period. I am worried, please tell me whether is this a sign of pregnancy? Should i take a PT if i don't get my period?? How long should i wait for it?
