About 6-7 days ago my boyfriend and i had sex, we dont use protection because I m on the pill and have been for almost a year now. About two days ago, i started having bad cramps. It felt like my uterus was weighted down and i could barely stand up or walk. Ive been feeling nausceaus, getting dizzy and even almost passing out. Yesterday i discovered light pink blood almost more of a discharge. According to my birth control, my period isnt due until the end of this month which is a few weeks away. The discharge isnt noticeable at all, i only saw it on the toilet paper while in the bathroom. I read about implantation bleeding and all the pregnancy sypmtoms. But i d feel at ease getting doctor advice. So i guess my main question would be, am i having implantation bleeding or just really early period signs? Does it sound like i could possibly be pregnant, or is it something else, like an infection of some kind?
