Hi, I had protected sex with my boyfriend on 26-5-12, had my periods on 14-6-12, have not had sex after 26-5-12, I took a home pregnancy test after around 15 days of sex as was a little worried and it said I'm not pregnant, but since 14-6-12 have not got my periods so I'm very worried now if I can be pregnant? I generally also have irregular periods. Please help,is there a chance I could be pregnant after the 26-5-12 act.

15 days is really a bit quick to get an accurate reading... try again in another two weeks... HPTs are very accurate by the 4th week after conception.

I agree wait at least another two maybe three weeks too test. And of course anytime you have sex there is a chance of pregnancy
