Hey ladies! My husband & I just had our first <a href="https://glowing.com/glow-fertility-program">IUI</a> on 11/15 (: We did femara & the pregnyl trigger shot as well. I am now 10 dpIUI & am having some pregnancy symptoms I think! Is it too early to tell? 
I have tender & very swollen breasts, acid reflux (which never happens!), an increased appetite, possibly urinating more frequently, & def cramping off & on! What were your first symptoms when you found out you were expecting? We have 3 days until we test!
