I had protected sex (we used condom) with my hubby on 12 may 2019 in my non fertile period and for more safety I took ipill also. within 48 hrs on 14th may 2019 my last period date was 20 aprl 2019. My period cycle was of 28-30 days. Should I have to worry about pregnancy? Can ipill delay my periods I took ipill last month also on 12 april 2019? Can ipill permanently stop periods?
