Ok recently I have been having stomach and low abdominal pains almost like cramps also from time to time I get these flutter feeling in my stomach as if I was pregnant I've been experiencing that since last February since I had my son but the feeling have been more frequent lately... I'm on birth control and my last period was the 3rd through the 5th of this month I did have unprotected sex on the 6th and 2 days ago I notice light bleeding I thought it was my period but it didn't last long at all every since then I've been having brown discharge I know it isn't time for my next period but I'm freaking out cause I don't know what's going on with me I've also have headaches... no migraines can someone point out some possible things that can cause this'

Call a doctor they would know exactly

Thanks!
