I am currently on the pill and take it everyday. The first day of my last menstrual cycle was on May 26th and then I started a new pack of birth control on Sunday, May 31st. My boyfriend and I had not had sex in awhile, and then on Sunday June 7th we had sex. He likes to pull out, so he did not ejaculate inside of me, even though I know there is pre ejaculation fluids. Then on Tuesday I started to lightly bleed dark reddish brownish blood. Could I be pregnant? I have heard of implantation bleeding, but it seems so unlikely, b/c we just had sex. I have also been really stressed out... was in a car accident and just moved so I don't know if my body is reacting to everything that is going on. I am really scared and confused... any help or feedback would be greatly appreicated. Thanks.
