Fist IUI with a BFP!!

I got pregnant with my son 2 years ago using clomid and metformin. I thought the same combination would work for my second child so I went to my RE and started the process. We tried for 5 months without success. I was ovulating each month but AF showed up each month right on time. We were going to do one more round of clomid, metformin and IUI. I went in to see my RE and do an ultrasound and she found a cyst from the clomid. Since I had a cyst, she said she couldnt give my clomid and that I needed to wait this cycle out. She told me to come back in 5 days later so that she can check my follicles. When I went in she said the right ovary had nothing and she couldnt get a clear picture of the right. She said to still BD but I was guarenteed to ovulate. I got a call from her the very next day. She said she got the results from my blood work and my levels went from 90 to 425 so she needed to do the trigger shot that day. I went in on friday for the trigger shot and went back on monday for the IUI. Around a week later I started to feel a little sick to my stomach. I decided to test a little early (13 days after my IUI) and I got a BFP!! I couldnt believe it. I went out to the store that day and got the digital test to read the word Pregnant and sure enough...PREGNANT!! Lots and lots of sticky glue needed... :) :) :)
