I had my tubes tied almost ten years ago. But my previous relationship was with a man that had had a vestomy. Now I'm with a man that is able to have kids. And we had sex the day I was to start my period. And now I'm late 3 days. I'm not under a lot of stress at all. And the day after there was a sensation around the area of my uterus. My periods are only 24 days apart and only last 3.5 to 4 days. And are panty liner light. And in the past ten years this is the first time I have been even a day late. Could I be pregnet
