What’s going on?

Hi! We have been TTC our second baby since the summer. My periods have always been on time, like set a watch to them (kidding), but that’s how predictable and on time they are. I ovulated Jan 1. Yesterday (day 25) I started bleeding. It’s not a lot, but enough to make me feel like it’s my period. I had some cramping but nothing like period cramps. My period is not due for another 8 days. Today, I have bleeding but no cramps. I am so confused, crushed and Dr. google is giving me so many different answers as to what it could be. Pic of last month into this week. Anyone give me any insight? I have my annual at the end of the month, if I am not pregnant by then I will bring up my issues. Thank you!
