I'm on follistim on day 4 of injections I went for ultrasound & they were growing highest was 14 but I go back today day 6 & they went back down 😢 what's going on? I'm never going to be able to do <a href="https://glowing.com/glow-fertility-program">iui</a> if my follicles dont want to grow even with injections...
