Pregnant! Iui #2

Soooo my wife and I decided to try again for another baby. We had an unmedicated iui in December but it didn't take. Jan 11th we had our second iui which was medicated (meaning I took the letrozole during my period with the trigger shot on Jan 10th). I tested out my trigger shot like every other day, by 8dpiui the line had disappeared...... naturally I tested again on 9dpiui and there was a vfl on two tests. On 10dpiui I took another line test which was darker and a digital which confirmed my pregnancy. I had a hcg quant blood test done on 11dpiui the hcg quant was 22. I had to retest that Friday the 25th which should've been my original test day, the hcg was 68. This will be baby #3 for us, our oldest is 10 and our youngest is 1 (2 in March).
