i've got muscle contractions in my fallopian tube n uterus, could this be an effect after 1day?

Right above, pregancy symptoms become obvious at the next ovulation cycle. I'd wait a couple of weeks before taking a test to make sure there is enough of the pregnancy hormone (Is it Hgc?) in your body, so as that you get an accurate result. If you are that desperate then get to the docs and get the morning after pill. He needn't have needed to ejaculate inside you for you to become pregant, as if he was sexually excited, the fluid which comes out prior to ejactulation (pre-cum as it is commonly known) can contain sperm.

If you were pregnant you would not get symptoms of pregnancy within a few hours after sex! You could be pregnant though if he ejaculated inside of you and you werent protected. Take a test to be sure and if you are going to have sex again make sure you take contraception so you can enjoy yourself without the fear of falling pregnant. Dont take risks.
