I’ve been using Glow for a while to track periods/ovulation. That’s how I got pregnant with baby #1. Fast forward to now. I’m 9 months postpartum, still nursing. Glow says my period was supposed to come 7/9-7/13 (today). I haven’t had any sign of it. I was sure I was going to get it yesterday because I woke up with a horrid migraine and that’s usually my sign. On Wednesday 7/10 I took two Clear Blue tests. One was an invalid test with no control window being activated and the second showed negative. I took a dollar store test on Thursday, also negative. Am I pregnant? Or am I really just this off on my period?
