hi i had unprotected sex at my most likely time to get pregnant on the 2nd, 3rd and 4th of september i took the morning after pill on the 4th, 62 hours into the recommended 72 hours, it now been just over a week and i was due on this week but ive only had some very light spotting today nothing else, my problem is im having a operation next week on the 19th but cant have it done if i dont have a proper period before then, i think its to early to do a pregnancy test. could i be pregnant and does anyone have any advice for me, thanks
