I just answered, I sometimes have to pace myself when a post is longer.
The HCG injection is fine and doesn't seem to sway. It can help us know when to have the three attempts, too! Have one the night of the shot, then again the next morning and following nights.
You don't HAVE to have the injection if you don't want, but it is ok and can be helpful to know when to have those attempts (much easier than OPK that's for sure!)
