Ovulation Bleeding? Implantation bleeding?

Ok so I’m really confused here 🤦🏼‍♀️ My cycles aren’t super regular, as I have Endometriosis and PCOS, AND I’m breastfeeding a 14 month old. But aside from ruptured ovarian cysts and implantation bleeding with my son, I’ve never really had mid-cycle bleeding.

I am bloated and cramping, as per usual for ovulation time for me... but I just noticed some bright pink (almost red) blood in my panties. According to my app, I’m 16 days into my cycle and in my fertile window. If the app is correct, I should ovulate Monday. Has anyone had any experience with this? Kinda caught me by surprise!

We had completely unprotected sex 9 days ago...🤦🏼‍♀️
