[briellav2010]

Hi everyone, in june my cycle was 30 days my menstraul cycle june 17-23 and in july my cycle was 30 days with my menstrual cycle being the 17-23 In August my menstrual cycle was the 12-19th. In august my supposed fertility week was the 23-28 I had unprotected sex once during my fertility week on the 26 and took plan B the next day which Was the 27th . Did my ovulation day get pushed further in date? After that the next time I had  sex was september 3rd and he came inside me now my period was soppose to come september 11 but it didn't I am 3 days late and took a pregnancy test this morning and it came out positive with the line being light. Can this pregnancy test be accurate 11 days after unprotected sex?? And did the emergency contraceptive I took on aug 26 push up my ovulation date??is this possible?

If you had sex in your fertile period in Aug, and your period was due to start Sept 11, then the you'd be taking the test 15 days after the first time you had sex. You ovulate about 14 days before your period is due, which would have been on the 26th...

Take another test and see if it comes up positive, or see your dr. The line being light is just because you're early in pregnancy, if you are in fact pregnant.

If your not sure your pregnant always take another test to see if line will be darker.
