I had protected sex on oct 18.it was rough.. two days later I'm cramping, I'm thinking my period came early but I had a light pink red blood it wasn't heavy... And it's still cramping as of now oct 28...I missed my period the spotting has decreased it only showed when I wipe it wasnt on my panties.. now I'm having lower abdominal pelvic pain... Sometime sharp am I pregnant? I've been stressing and depressed for the past week while this was happening
