So I got my period in early June. I had unprotected sex with my bf 6/18/16 and have been jus about every weekend since then but we had sex several times up until the morning I got period july on 7/3/16 and it stopped 7/5/16. Well last night I felt like I was cramping a Lil and then today after using the bathroom I see blood after wiping myself its light but I can see it. Could I possibly b pregnant?
