I have been with my boyfriend for over a year and i made a stupid mistake drunk and had a 1 night stand early hours on the 27 th march this year i found out this month april 11th i was 3+ weeks pregnant so am not sure hu the dad is if i was pregnant to the one night stand shouldn't the test say 2 weeks as 27 th to the 11 april is not more than 3 weeks plus i did take the morning after pill the day after i had a one night stand on the 28 th of march , but i still not 100 percent its just crazy how all year av been with my fella and march i get pregnant and had a one night stand , i calculated my last period which was the 4 th march so i used a due date calculator and it showed days where i was fertile and he day i may of conceived and it showed dates before the 27 th (one night stand) It said i conceived around the 18 th so i may already of been pregnant before the 27 th i am so scares and worried but when i took the clear blue the test said i was to far gone for it to have been the 27 th march ?????
