Help please

Ok I don't know what to think. I don't have normal cycles. I haven't since coming off bc last year. I have to take pills to have a period. I thought today would make me 15dpo, but I may be wrong. I've never been able to pinpoint ovulation accurately. Anyway, twice today I've noticed very faint light pink when I wiped and I'm having small cramping on one side. What is going on?
