first month of iui

so me and my husband have been trying for our second child for about 6 years and we have started out first round of iui this month. I started off with femara, then injected with gonal F and now using progesterone. I really am hoping that we only have to do one round. but these next couple weeks are going to be hard. I hate taking pregnancy test because 99%of the time they are negative but hoping for the best this month. and if we are pregnant it will be a good birthday present for my hubby in September! anybody else going or had gone thru an iui?
