Opks are all over the place?!

Hi I'm on cd19 after a chemical that I lost at 4w2days, and confirmed HCG is out of my system. My opks don't seem to be progressing and they seem to be all over the place! Only symptoms of O is ewcm the past 3 days but now my cervix is hard and closed, yesterday and day before it was high and open and really soft.

Is it normal for opks to be all over the place after a chemical? My FH and I have been baby dancing nearly every day for the last 10 days trying to catch the egg.

Any advice? Thx!
