What’s happening?

I’m irregular on my period since coming off the pill in December this is how my cycles normally are… anyways on cycle day 35 which was 10 days ago I had spotting for 2 days like these pictures was only when I wiped didn’t need a pad or anything, then I’ve had nothing. I read that it could be old blood before a period but surly not 10 days before then not have anything for 8 days.

My nipples have been so sore for about 5 days and today started with watery discharge.

I also went out drinking yesterday and was sick which I never am after drinking.

We’re not TTC and have been using condoms (I know they’re not 100% safe.) he always checks when he takes it off that it’s not split.

Does anyone know what could of caused this discharge/spotting??
