Hi, the last two times I've had sex I've started bleeding. The first time I went to a GUM clinic, and the tests all came back negative so I thought everything was okay. The second time there was a lot more blood, and when I went to the doctor the next day she looked for erosion or something, and said there wasn't any, so thought it was probably hormones. I have come off the pill since. This was in like the beginning on September. Then just a few days ago I was fingered and there was blood again. Any idea what this could be if it's not an STI and there's no erosion? Thanks.
