Hi everyone! Im so confused..... According to Glow, I am supposed to start my period today but I've been taking opk's twice a day and I got these yesterday and today. I thought I ovulated sometime between 6/17-6/21 (cycle days 10-14) my husband and I went on vacation and forgot the opk, so I am just assuming. Has anyone gotten a positive opk this late in their cycle?? Today would be cycle day 29 if I don't start AF.
