Confused, need advice

OK so, ovulated CD 9 according to my digital opk, had EWCM, good to go, BD that day, then EOD for rest of fertile window. Yesterday, wiped and saw what looked like clear, cloudy ewcm, weird, but BD last night because opk can always be wrong. Tonight, having cramping, especially on left side like almost ovulation cramps, so took another opk, CM watery, blank circle. Feeling blah, like tired and almost sick feeling, husband says I feel very hot, so took temp 97.9. Should I BD tonight in case opk is wrong, or am I feeling something else?
