I started hcg injections yesterday. I messed up and put 5 mil in powder bottle and should have only done 2.5 mil doc said just double the dose for rest of bottle. So I did 125 iu and should have had 250iu. So today I doubled dose and did the 250 like I was supposed to. I've noticed I've got sinus pressure today. A Lil groggy feeling..is that normal? Thanks for the info this site is great.
