1st IVF cycle

I just gave myself my first injections of my follistim and menopur for this cycle. I’m extremely comfortable giving myself injections since I give cats and dogs injections everyday at my job. The scary part this time was not knowing how to use the follistim pen. I️t took be about 20 min to watch the videos about the medications and another 20 min to give them. I was shaking the whole time for some reason but I did I️t! I was suppose to give 112.5 units of the follistim but I️t only had two marks in between the 100 and the 125. Hope I measured right. Will have to double check with my nurse tomorrow.
