I had sex one day before my period .. My period came .. After sex I went and pee no burning or anything .. When my period came .. It was lighter then normal .. At times and then like the color wasn't exactly the same it was a little more orange an then sometimes it would be more of a redish .. And I would have very little cramps on some days ... Now it's a week later & my pee still burns and I have lower stomach pain .. And I feel sick a little nothing change really in my body .. I have to pee more but I can't get it all the way out .. Can I be pregeant ?
