Hello Doctor,
I just wanted to know if I am pregnant or not... we didn't have sex... but my boyfriend on my assline... I have had 3 normal menstrual cycle after that... I have also taken 4 pregnancy tests... first one on the first day of my first menstrual cycle after the incident.. second test on 2-3 days after my first menstrual cycle... third on 10-15 days after my menstrual cycle and fourth just before my third menstrual cycle all shoed negative results... is there any chance that I am pregnant?

You claim not to have had sex and passed a further THREE cycles, so odds are against any sort of pregnancy.
You do understand how the procreation process works ??

If you have not had vaginal intercourse then you likely cannot be pregnant.

Reading between the lines a bit... but it sounds like there were having butt fun and if that is correct... its not much of a stretch (pun intended because they ARE very close) for it to become a real possibility. But 3 months later... highly unlikely unless she is one of those rare ones and has bleeding that mimics a period and that won't test positive until the second trimester... ASSUMING she was taking the test at the right time in the right way... (high likely hood its not being taken the right way and right time)

Considering you had 3 periods, it is safe to say you are not pregnant. If you are not ready to be a mother, please refrain from risky behavior or at least use contraception.

If he ejaculated on your bum crack, assline, or whatever you wish to call it, there is a chance that the semen managed to come in contact with your vagina and cause pregnancy. Just a warning, anal sex can lead to pregnancy but it is exceedingly rare for it too occur.

Second point, the surest sign of pregnancy is a missed period. If you're pregnant your body isn't going to menstruate. That being said, you've NOT missed a period thus are probably not pregnant.

It might be wise to investigate birth control options if you're starting to explore sex. Even anal sex should require a condom because Sexually Transmitted Infections can be transferred through anal sex. It is better for you to preserve your health regardless of the male involved.
