After a year and a half of having cycles anywhere from 9 to 22 days, I finally went to the doctor! I got a prescription for levothyroxine. Last month, my cycle was 24 days and I could feel I definitely ovulated. This month I could feel ovulation again. At CD 24, despite having zero symptoms, I decided to take a test, on my 25th birthday, and it was very positive! My first baby!
