1st IUI- questions

Hi everyone! This month is our 1st IUI. Today is day 3 and the ultrasound and blood came back fine>. I picked up the 3 medications needed for this cycle. Clomid 100mg, ovidrel(trigger shot), and progesterone capsules (vaginally). The question I have is about the progesterone suppository. Im half embarssed, but want to know. I was instructed to insert 1 capsule twice a day. How long does it take to dissolve? And can we still have sex during that 2 week time frame?
