Ovidril/ day 10 tww

So I did Ovidril shot 10 days ago tomorrow. I am feeling pressure/bloating I guess it is. Though I have had some constipation do to iron pill.  Hoping this is a good sign. Trying to hold out Christmas Day to do a test. Also the day AF is supposed to show her ugly face. This is my fourth round of Clomid and Ovidril. Would it be too soon? Really would like to surprise husband.
