Hi ladies -I'm using my GLO app and love it! My fertile period was set for Thursday. My highest day was set for Monday 11/9. When I tested Wednesday using OPK tested low fertility. Then Thursday I tested and jumped right to Peak. Skipped over high all together. Is this normal? I updated glo and thank god my husband and I have been having sex all week. I'm just curious if it's normal to jump from low right to peak days.
