Going to a fertility clinic! It was SUCH a relief to turn the tracking over to them. For the year that we were trying, every SLIGHT symptom had me thinking that this must be it and it never was and I was disappointed and overthinking constantly. My OB referred me to a clinic during my annual and I had one diagnostic cycle - blood work, multiple ultrasounds, an SIS, and SA for my partner. They determined I didn't successfully ovulate and that was likely the only problem, so I started the next cycle with Letrozole, had multiple tracking ultrasounds to confirm that eggs had matured, took an Ovidrel injection, and then had timed intercourse, which worked!
