Increased Discharge?

My partner and I decided to let life happen-- not trying and not trying to stop anything.

Acccording to the app, my fertile window was 9/27-10/3. Due to working opposite shifts, we only had sex outside of those dates (9/23 and 10/4). My last period was 9/19.

I have noticed an increase in discharge that's like milky...almost like I have to change my panties since there's a good amount of it.

Could it be just my period coming or could I be pregnant? I know I can just wait to find out if AF shows but just hoping to get some insight as normally I'm pretty dry right after ovulation.
