Help.... Opks?

So these are my opks today! I had only been using the blue equate opks, but I got some of the digital advanced to try! The pst two days I had no smiley and today the smiley is flashing! How are accurate are these? My temps are low today, lower than they have been all cycle, I have watery/creamy CM but no EWCM, and my cervix isn’t open! Last cycle I had five days of a wide open cm and gobs of EWCM for five days before I ovulated, can that chance cycle to cycle?? Sorry for all the questions, I don’t ovulate regularly! I did a Femara cycle in Sept and conceived but MC at 6 wks! So I am nervous! I want to ovulate again so bad but have never O’d two cycles in a row! I am just on edge! Anyway any insight appreciated! Oh I took the other wondrous opk just because I was curious!
