Marching orders

Just got the afternoon phone call. For those playing along at home, my Estr.adiol level is 131 (no clue what that means), and she confirmed that I only have the one viable 14mm follie. There are few others sprinkled around, apparently, all really small, under 10mm. The nurse told me to stay on 75 units of F.ollistim and come back in Friday. She said the doc wants it to be 19 or 20mm before triggering, as long as my blood tests don't indicate that I'm going to be ovulating on my own. She thinks we'll insem on Monday or Tuesday (???). I forgot to ask her if my Hep vaccines would affect the Hep test. I am going to choose to not worry (thank you, Inloco and Cali).
