me and my bf had sex unprotected and he came in me over a month ago two weeks later i was having cramps and i was getting sick in the mornings the smell of food would make me sick i took an early response test and it came back negative but i believe i took it during the week that i was suppose to be on my period. i usually get my period the first week of every month this month i did not get it and 5 days later after my missed period i thought i had got it because i started spotting it was lighter then when i am usually on it and it was pinkish brownish and it stopped two days later the third day it was just spotting no use of wearing a pad no more. i am having cramps and headaches im only 18 and i dont know what this all means i am freaking out. Please help me !
