Hello all, i just wanted to know if any of you could help or share experiences with me.
Been ttc for 3 months and 1st month i ovulated cd16, 2nd month ovulated cd18 and 3 rd month i am on cd24 with 9 days of high fertility and still no peak. Is this normal??! Only had my mirena out in dec so these months are the only cycles i have for reference. I am a bit worried. Any comments are appreciated.
