4th Ultrasound and blood work

I came in today and Dr. Anderson was back from vacation. He looked at my chart and came in my room and said "well, it looks like you won't be having twins" commenting on my 1 and only follicle growing. He said I was ready for an IUI because the 1 was grew a lot just overnight. So the nurse gave me the HCG shot and sent me on my way.
