Hello, so feb 18 i had unprotected sex 6 days later i got my period (my cycle is about 21-24 days long but very irregular). I had unprotected sex on feb 26 (day after my period), march 10, and 12. today is march 15 and i took a pregnancy test and it came out negative. I feel sick quite a bit, i feel rather bloated, my breasts have slightly enlarged, what i would really like to know is if you think i am pregnant
