I had protected sex 3 days ago and it was my first time. I am not on any birth control and I have not taken Plan-B or any sort of morning after pill. Is it possible for me to feel pregnancy symptoms (i.e. nausea, change in appetite, tender breasts) this early? or could I just be paranoid. Also, if I take an emergency contraception now, would it still have an effect on me? I am very scared. Please help.
Relax. You wouldn't experience symptoms that early, if you were protected and took all the necessary precautions I really wouldn't worry too much. As for the nausia and other symptoms it may just be your nerves making you feel that way. As for the tender breasts, if you are close to your period or ovulating this can make them tender and swell up a bit, in turn they will become a little sore.
