HELP!! IS THIS NORMAL?!?!

Okay so before y’all say it’s an STD or STD related. I got tested in the end of April. And everything came back normal. So I really really doubt that’s it. Anyways this has been going on for about a month since like the middle of May but it comes and goes and there’s only some itching sometimes, that comes and goes too. It’s really not the first time I’ve had yellow discharge but white discharge is what’s normal for me not yellow. My period is due either tomorrow or the next day according to the Glo app so maybe that’s the reason for the little blood but tbh I’m not even sure.. Please help.. Has anyone experienced this ??
