I use the clear blue advanced digital OPK. This is my 2nd cycle using them. Last month I kept getting the flashing smiley face which means high levels but no peak for 10 days. Ended up getting my period and started the process over again. After 6 or 7 days (lost count) I finally have a solid smiley face.

I definitely suggest these since they have a little computer chip that “learns” you hormones. They are a bit pricey but I get the box of 20 and end up having extras left over for the next month.

Hubby is excited to and putting “in” his effort lol sorry silly joke.

Now the fun and waiting games begin.
