Ok so I went off my period like three days ago right and me and my boyfriend had unprotected sex last night and once this morning. Her didn't pull out either time and this morning I went to the bathroom and wiped and I was a tinge of blood.. Was it because my period was recent or??? I don't want to be pregnant. I didn't think it would be possible with my tubes clamped its almost been 3 1/2 four years.. What do you guys think?
