I’m 19 and have been TTC since a miscarriage in June. I went to my OBGYN a couple weeks ago bc I noticed my BBT charts weren’t showing ovulation and my cycles have been whacky. They did bloodwork (found out I’m anemic and had extremely low levels of Vitamin D) and did an ultrasound. But when they did the ultrasound, I tried to explain it to the nurse, who told me that BBTs don’t really mean anything and that women who have anovulatory cycles would have very sporadic periods (which is exactly what I told her was my reason for being there?).
