Hey ladies, 41yrs old ttc goin on the second month. First month using preseed. Glow says my fertile window is now started yesterday ends Saturday but still all opk says negative(no smiley face at all). I'm seein my gym tomorrow routine.anyone have advice of what I should ask him to check for me to maybe help the process. I really feel like I'm new to this all over again my daughter is 18yrs old.bf of 11yrs has no children at all he's 10yrs younger. I am really afraid maybe I missed ovulation but I've been testing prior to what glow says on dates. AF DUE 2/16 according to glow. Can my gyn see when I'm ovulating?
