Me and my partner had unprotected sex last night, after we finished I went to clean myself up and when I wiped there was a really light pink discharge, I’ve been to toilet today and there wasn’t anything there either. I did google but he only thing that came up was implantation bleeding or irritation, we’ve been having unprotected sex a lot due to ttc, this is the chart. I don’t think it could implantation bleeding could it?
