Okay, I had unprotected sex. I took the day after pill a day later. I have had some symptoms but I think it is all in my head I have had a period twice my period are never heavy so I wasn't sure if it was my period of not. And I have had 7 negative. Pregnancy test. I just need somoene to reassure me I'm not pregnant.

Of course no birth control, even the morning after pill is 100 percent, and of course the morning after pill can cause issues with your period for a short time.

How long ago has it been ( two months?? )

Two periods and 7 negative pregnancy tests. I'll go out on a limb and say that I'm 99% sure that you're not pregnant.

Of course there is that 1% left over. ;)

Sex=babies. Stop taking chances, then you can worry less. Not stop worrying, but worry less.

As Chuck said, no form of birth control is 100%, but at least lower the odds.
