On December 23rd me and my boyfriend had unprotected sex and he ejaculated and on the 24th I took the morning after pill. On January the 8th I started to bleed and it lasted four days. On the 3rd of Feb I took my period again and it ended today on the 8th, but this morning I suddenly felt as if I had to be sick? I was sick this morning and after I was sick I felt completely fine!! Am I pregnant? Or is there something wrong with me pls help
