Pregnant or weird period???

Long story short I’m on birth control but I forgot my pill pack at home during my placebo week when I left for my parents for a month so I just waited to start my next pill pack until I got my period. I got my period and then started the pack the day of my period and it didn’t end until the 2nd week(which is normal for me). Because it was so long I skipped the placebo week and just went straight to my next pack.

Now I’m on my placebo week of that pack and it’s the 4th day and idk if I started my period or not. It’s super light pink, basically discharge but it’s tinted pink/brown. And I have no idea if it’s my period or if it has to do with my UTI I currently have. Normally my periods are dark brown but Rn it’s pink discharge and I’m scared that this could mean I’m pregnant??? I have no idea someone please tell me this is normal.

Side note: I had sex after the 2 week period and he pulled out
