The symptoms are not in your head. The injections make your body think you are pregnant.
Don't give up, I just had my first IUI after nearly 9 months of ovulation induction and I got a positive result the doc said that she knew she could get me pregnant but it could take 12-15 tries :/
I have other factors that gave me a time limit do I'm praying for this one to be a little baby in 8 months.
