I had sexual intercourse multiple times from 4th to 7th of april and used emergency contraception called i pill as precaution to avoid pregnancy. I took the pills on 5th and 9th. My last period was on 9th of march and hence i am already 4 days late for my period this month. There has been vaginal bleeding for the last two days but i am pretty sure that isn't my period as the bleeding is very light and there are no cramps as compared to my regular period cramps . Technically we had the intercourse after my calculated ovulation phase and my partner also pulled out everytime. Although we are pretty sure that my partner didn't ejaculate inside me , we did notice white fluid on my cervix after sex but we aren't sure if it's from me or him. Should we be concerned about possible pregnancy? What's the next thing we should do right now?
