Lots of creamy CM!!!! CD23 could it be?

I don't know when I ovulated have a consistent 28-29 day cycle. Last couple of days I went from diarrhea to now constipation. Sharp pains in my left pelvic area, and lots of creamy yellowish CM! Also feeling small twinges by my belly button. What's your thoughts? When should I test? AF due 03/20!
