Hi, i am 24 yr old female, my fiance and i indulged in sexual activity, it was 6 days before my ovulation(i map my cycle using an app according to which it was a safe day) where in he did not penetrate inside me but was around the opening, he did not ejaculate was mostly just precum, both of us were wet.within next 3 hrs i took an ECP(ipill).however i did not get any withdrawal bleeding. the first time i took an ECP about 2 months earlier just 2 days after i got over with my periods i did experience it.

my Periods are 4 days earlier but the flow is very less and has a brown tinch to it.do i run the risk of getting pregnant.kindly help pls.
