Okay so the day before yesterday was the last day of my AF(cd3) . I started doing my opks yesterday... it was low.... but today just two days after AF (CD5)I have a flashing smiley.... so it's high... is that normal?? To have a high this early? This is only my second month TTC and last month I went from low to peak I never even got a high... and I ovulated on cd12... so this all seems a little weird to me lol... I have 25ish day cycles... any feed back wanted!!!! I just need some answers or some stories because I'm confused. Thank you ☺️😘
