Supposed to be on my fertile week from 12/13-12/20. I woke up to use the bathroom on 12/15 and I’m having another period. I added this to glow and it change my hole schedule. Now it’s saying I ovulated the 7 and 8. I’ve literally had two periods within 2 weeks. Is this normal? I just feel weak. And this is devastating. It won’t even let me add the fact that I started my period on the 15 because its to close and I ended my last period on the 6
