So. I've been using the Clearblue Advanced ovulation kit. I love them but they are pricey. here is my situation.. so I start Clomid next cycle. & doc said I didn't need to use OPKs but could if I wanted to just make sure. do I buy one more CB kit in hopes this will be my last time to buy. or try some of the cheaper options. advice, recommendations & opinions welcome. also adding. I normally ovulate later. like CD 20. I normally have like a 34 day cycle. But he wants me to take the pill CD 3-7 & then BD 10,12&14.
