started stims early

Well I went to the doc for US and I had a couple of follies growing.  Doctor had me start stims same day because he  didn't want one taking over the whole cycle. So went home and realize that they pharmacy hadn't sent us the needle to take the HCG. Of course I freaked out but was told that I can hit the local Walgreens and buy needles. The Letrozole gave me a horrible headache that lasted all day today. Feel a little bloated. I pray that everything is good on Monday!
