IS THIS NORMAL? 😕

I've been on BC for the past 10 years and went off Nexplanon early Jan 16'.. I've had pretty regular periods since getting off BC.. but this seems out of the ordinary. I've NEVER had short cycles like this. My main concern is during my last AF cycle, ClearBlue Digital OPKs said I was "HIGH" fertility on all days! How is this even possible??? Still today, it's saying HIGH. Plz any advice would be appreciated! I feel so bloated, hungry, tired and irritable. 😩
