2 weeks ago my boyfriend and I were experimenting when he put the tip in. I don't know if he came or not but he told me he didn't nor did he prenut. But to this day I am experiencing lower back pains ( which could be from doing 200 crunches last week) constipation headaches and slight fatigue. He only put it in for a few seconds and it wasn't that far. I was a virgin so I think I am over exaggerating. Also I had 2 large milkshakes which could be why I am constipated. What has me worried is my vaginal odor has vanished and a white substance I get a lot before this happened has appeared. But my period doesn't come for maybe 2-3 weeks from now. Am I pregnant or over exaggerating?
