I just went to my doctor this morning for my day 3 blood work and ultrasound. this will be my third <a href="https://glowing.com/glow-fertility-program">iui</a>. they told me to continue on my 5mg of letrozole days 3-7 and on day 7 I am to go back in to pick up my injections of puregon. anyone been through this and have any advice? how did the shots make you feel? did you get pregnant? I just don't know if I should do another round with just the letrozole or should I go the extra step and do the injections as well?
