at the beginning of the month i forgot to start my new pack of birth control pills so instead of starting it late i just didn't take them. me and my boyfriend use the pull out method and i heard it was hard to get pregnant at first after stopping the pill so i thought i would be fine. my period is about a week away but lately i've been getting really nauseous for no reason and i have a horrible pain. its been 3 days now. it felt like it started in both my tubes...a really bad pinching pain and moved towards the center and now my uterus just has a throbbing pain. this pain isn't like premenstrual cramps. i went to the doctor today and the pregnancy test came back negative. she did a vaginal exam and said my body didn't seem like it was going to start menstruating anytime soon. does anyone have any idea what this pain could be. the doctor said it could be implantation but we would have to wait to find out. any ideas? i don't think i can wait much longer for her to figure out what is going on down there.
