Trigger shot today!!!!

I had another follicle scan this morning. Three good sized follies - 1 at 18 and two others not far behind; lining is a 9. I was given my trigger shot and instructed to bd and start progesterone gel on Thursday. Holy cow this might really be our month!!!! I know not to take a hpt until the trigger shot is out of my system. Any side effects I should expect from either the trigger shot or progesterone?
We aren't telling anyone our news (told them after a previous scan that follies were too small - at the time they were, but not that we were continuing meds and monitoring) so you all are my only sound board. Any suggestions, advice, well wishes appreciated.
