I got my periods on 15 Dec and on 18 I had unprotected intercourse n I took unwanted 72. I had protected sex on 19Dec and 20 dec.. I bled on 25Dec again fr around 4 days .. it was although a light flow..similar to periods but d flow was not heavy.... I had protected sex on 8 9,10 Jan ( any 2 days amongst these I dun remember exactly)... so according to me I should have my periods by 25 Jan to 26 jan .. but today is 3 feb and I haven't got my periods yet... I did pregnancy home kit test on 28th Jan ( it wasn't d frst urine, but it was on a gap of around 6 hrz) it came negative... I got a lil mild abdominal pain around 5 days earlier.. but haven't got my periods yet... I m around 10 days due..... do I need to worry??? wt could be d reasons?
