My period ended February 23 . Right after my period ended we had sex Sunday night and I notice after intercourse I wipe off with a paper under there and it had yellow discharge . And then again we had sex again today and then like little blood too After I was done having sex like I’m confused and ? I’m concerned about my period like what’s going on . Good thing next week I got an appointment with my doctor .
