Is it too early to test? I’m 12-13 DPO and AF is in 3 days. I know you’re supposed to wait until the day of your missed period, but I had horrible cramping at 10 DPO with very light brown spotting. I’ve also been extra hungry, tired, lower back aches, and nausea (which is weird because I never get nauseous except when I was pregnant the first time.) I don’t want to test early and get disappointed with a negative. Anybody get a BFP at this point?
