Femara 5mg

Hi ladies, I'm doing my second round IUI with Femara 5mg+ Ovidrel trigger shot. The first round was a failed natural IUI with the trigger shot. I had 1 follicle measuring 18mm that round without medication. I'm concerned if the 5mg is a high dose to begin with, for someone who ovulates on their own. I'm anxious about hyper stimulation. My clinic doesnt start with the lower dose of 2.5mg femara for some reason. Also, I wanted to see if baby asprin is necessary. Please share your thoughts about it and success stories with the Femara 5mg+IUI+trigger.
