Hi.. my last period was on 27th march. and today is 15th May. i took allylestrenol for three days as 1+0+1. And after consulting with my doctor she gave me norethisterone for five days as 2+0+2 and adviced me to have a pregnancy test. after getting negative pregnancy test, i started taking the med on 07th May to 11th May. but still my period is not started. My question is: is there any possiblity of getting pregnant and the period is delaying due to the medicines
