So I did not take my birth control at all the last two days of the third week. That was Friday and Saturday. Later on between Monday and Tuesday the following week I had unprotected sex with my boyfriend four times. He pulled out though and did not ejaculate in me. That same Tuesday I started my period when I was supposed to and it lasted 6 days like it normally does. Now two weeks later I'm just a little paranoid that there is a chance that I could be pregnant.
