If in the extremely likely event that I don't get a BFP this cycle, I'm thinking of investing in a BBT thermometer. I use OPK's and track my cycle on an app, check my CM and also sometimes, my cervix position but I know the only way to really figure out when you're ovulating is by doing BBT.
Can anyone recommend me a good one? I've seen some cheap ones on Amazon but I don't know how accurate they are.
