Anyone using Clearblue digital?

It’s my first time using OPKs and my doc suggested we go for clearblue digital. I usually have a 30-34 day cycle. My LMP was feb 9th and I haven’t tested positive opk till date.

As I’m going through posts here, there are people talking about testing twice a day. I didn’t do that so is there a chance I missed my ovulation?

I’ve a history of a miscarriage in September and borderline pcos post-miscarriage. Worked hard to shed a few calories and get hormones to act normal again.

Really want to get pregnant soon with our 1st one but getting a plain circle everyday has been extremely disappointing😭😭
