Last month the condom popped while me and my boyfriend was having sex, but my period came and lasted 5 days and it was normal and it always stay on for 5 days. When the condom popped he didn't nut in me. This month my period was short. Monday jan 18th 2016 it came on and turned brown the next day. Wednesday i didn't see anything. I started to feel nauseous but it felt like it was in my throat. I have little cramps and i started to have slight headaches today. I also have been feeling cold. Yesterday it felt like a fever was going to come. On friday i had a pink discharge and then i had a brown discharge with a little pink color mixed in it in one spot. Am i pregnant?
