TW: picture included

My last period started on 11.7. and ended on 14.7., there was no old/new blood after that. On 18th or even 17th, after sex, I noticed something I thought was brown old blood but it continued up until today. It’s not brown (it’s more on purple/gray scale), and my discharge was a bit pink last night + the purplish specs. I thought it was spotting, but it’s too early. Thought it was because of sex, but it’s been more than 4 days since I last had it. It’s not UTI (I used vaginal cream for UTI with no help). OBGYN told me to come only in 10 days when the cream effect goes away, but I’m sincerely worried because I had benign tumor on my ovary few years ago.
