I have a concern that's causing be to feel ill and sick with worry. A story that I'm not very proud of but I've read feeds in the Internet which have just fuelled it. I had anal sex with a partner, at the time I thought my period was due (very irregular, turned out it wasnt) so popped a precautionary tampon in to avoid any embarrassment. We had anal sex, to my knowledge it was all tidy but I'm so worried that this could result in pregnancy. Ive read a barrage of horror stories online - I need to hear other thoughts?
