Weird cycle after provera

First cycle after provera and I’m feeling all wonky. Here’s a summary

-got a positive opk on CD 7 but I was extremely dehydrated from being very sick. Maybe that caused it to lol positive?

-didn’t have sex at all because of being so sick

-had no other signs of ovulation at that time

-it’s now CD 20 and for the last 2 days I’ve had EWCM and cramps which is more in line with ovulation for me

-haven’t had a positive OPK since CD 8

QUESTION - Do you think it’s likely that I tried to ovulate earlier in the month but never did and this is probably it?
