Hey ladies, about to start again try for last baby no 3, I need help <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> , what’s the best way to track bbt with an actual tracker attached to me constantly, for the life of me I can’t remember what they’re called!! Which is the best? I don’t really want to have to take temps myself every morning as I’ve an 3 year and 8 month old that can disrupt my sleep lol thanks 💕💕
