Suddenly bleeding after sex

Wendy

My husband and I have been actively trying to get pregnant since around October. Last month, I began tracking my ovulation for the first time. A few days after my ovulation window had closed, we had sex and I saw blood on the tissue afterwards when I went to the bathroom. It was only a streak so I didn’t think much. A day or so went by and we did it again. Once again, I bled afterwards, this time a little more. It’s been a few days again and we just had sex and I bled again a little more. It’s not rough sex and it wasn’t painful so I’m pretty sure I didn’t tear anything. When I googled it, it said bleeding after sex could be a sign of implantation. I wanted to see what you guys thought. Thanks!
