Cramping after ovulation

mia

2 days after ovulation (according to BBT, CM and 3 diff apps ) and I’ve cramps. This is the first time I get them but have only been noticing these things since 2 months ago when I started charting and all. Just wondering if it means I’m only just now ovulating? Can one ovulate more than once in one cycle? Could I be getting my period so close after ovulation? Thanks a mil!
