I don't have a BBT thermometer, and the idea of sticking my fingers up my vagina every day to feel my cervix kind of seems like a lot of work. How do I know when i'm ovulating or not, besides telling from my cervical mucus? I've been on nexplanon and I just got it removed, and i'm guessing my cycle could be irregular for a bit, and I don't want to get pregnant yet. I guess my question is, how accurate is Glow's calendar when it says you're ovulating? Is that just a guesstimate or is that the same for every woman or what? I suppose I could buy a BBT thermometer, because it's cheaper than using OPKs all the time (or so i'm assuming). Thanks in advance!!! Xxx
