I am 17 and I recently had unprotected sex, now I am bleeding it looks like a period but doesn't at the same time, also I already had My period which stopped around My birthday (Jan 14th 2013) , It is bright red there are a few clots and every once in a while it looks like my uterine lining shedding :S, the next day (today) it was a light brown/pink-ish color but later through out the day was red-ish again I am so confused, could I be pregnant? , is it still possible? , Help -.-
