I'm 18 years old and I think i'm in trouble my last period was about first week of april I think the 6th was first day it ended about 10th and I had sex on my boyfriend b-day the 18 we forgot to use a condom and i'm not under any birth control at all. My periods are pretty normal give or take a few days but now i,m seem to be spotting which I expected to turn into a period it has not its just faint brown stuff and maybe a little red I told my cousin because I have never had this happen and she told me that when she was pregnant she had the same thing only it was implantation bleeding i'm not sure what that is? And my boyreind and I just broke up and I dont want to freak him out he,'s grounded and may not graduate from high school and I just got into 3 colleges and am trying to make a decision on which to go to and ever sice my cousin said this yesterday i've been going crazy. Should I take a pregnancy test? She said to go to the doctor but I dont want to tell my parents unless I am. I thought it might be weight loss but that was barley 5 pounds and I have dropped more with no period problems. I have funny cramp and feel sick and my boobs feel little werid. I'm scared .
