TTC 4 years.

We started out just whenever it happens it happens, then two years passed and we are like? Why hasn’t it happened. Mind you I was 20 at the time and husband was 20 as well. So went to obgyn and done hormone test and trans vagina Ultrasound during when I was close to ovulation and they said I was about to release an egg so everything looked good. To keep trying we are still young and have plenty of time. So I was happy about that, two years later and still nothing. Setting up another appointment to figure things out. My husband does have a lil low sperm count but not significantly low. Blahhhh soooo it is so disheartening to get that negative, I would be happy to just see an evap line or something!
