"ovulating" but there's blood?

Okay so I just started the mini pill 2 weeks ago and I tracked my cycle before and now I would have been right in the middle of my fertile window but there was some pink spotting yesterday and then late last night I started to see blood but darker and now I'm seeing a dark red discharge but like it's more mucus-y (I'm sorry tmi) what is going on? Edit : 🤦 I know I'm on the pill but I was just mentioning it in case that would help solve my mystery...
