Measuring follicles and trigger shots

Hi ladies,

Today I am 13 DPO and I tested my blood this morning and got a BFN. ☹️ We’ve been trying for over a year and this was my second round of Letrozole 2.5 mg. I’m always in here reading about you guys experiences with both Clomid and Letrozole and I’ve noticed that a lot of you speak of the doctors measuring your follicles and giving you trigger shots and I wanted to know at what point did they bring this up to you because my doctor hasn’t said a word about it.

Also while you guys are here have any of you had success when you tested negative 13 dpo? What day did you get your positive?
