The range has been 18-37 days for ovulation - yup, that's a lot of OPKs!Jul 17, 2022 · OPK or BBT? Curious to hear others experiences when they were TTC. I have been doing both OPK tests and measuring my BBT for several months and I’m noticing that I’ll get a positive OPK but then my body temperature won’t spike for sometimes up to 4 days later. .
