my cycle started on June 4 and ended on the 7th of last month. according to Glow, I had sex right around my ovulation time last month. I should be starting my period any day now but I've been noticing some subtle differences that aren't normal for me around the time AF shows up. my areolas are darker, my nipples hurt, (which my breasts do tend to hurt sometimes right before I'm about to start, but not usually my nipples), extremely tired, slightly heightened sense of smell, a little more moody than usual, slight loss of appetite, (although I do get hungry, just nothing sounds good), and some lower back pain. Could this all just be AF on her way or could I be pregnant? I didn't wanna get a test quite yet because I haven't technically missed my period yet, at least according to Glow. thoughts would be greatly appreciated!
