My ex and I had sex without a condom roughly 3 and a half weeks ago, his doctor told him that he has 'super sperm' meaning that he can get someone pregnant very easily. Anyway, we had sex and the next day I took an emergency contraception pill (morning after pill) and we had sex again about 3 hours after that but this time with a condom. My only worry is that after we had finished having sex there was some of his sperm on his bed cover...... I don't know how it got there, it was wet so it was fresh from that day. About 6 days later I took a pregnancy test from the shops and it came up as negative. But I'm experiencing some signs of pregnancy that I've read from the Internet - nausea, mood swings, heavy white discharge, sore back, but my breasts aren't very tender but the Internet said that most of these side effects don't come up until late 6 weeks, so I don't know. .

I'm 17,
