Alright, so, around May 23rd up until the 1st of June I was having unprotected sex with my now ex boyfriend. Since then I have experienced neck pains, headaches, slight cramps on the right side, I have had a little bit of bleeding, it only lasted three days, was a light pink for the first two days and then turned a sort of orange color the third day. I've had emotional outbursts and a lot of gas. I haven't been horny like I usually am but tonight I decided to masturbate to relieve some stress, while doing so, I noticed on my vibrator there was brown blood, and then when I continued because I know brown blood means old blood, it turned a red color. I took 3 pregnancy tests around 5 or 6 days ago but they all came out negative. I'm not suppose to have my period until the 16th. I am concerned that I am pregnant. Please help. Thank you so much.
