Yea, thats how it usually goes. Before I talked to my heart doctor he told me that I would probably have 2 ultrasounds, if there were no problems. However, since I found out I was pregnant, I went in twice for bleeding, and once for cramps, they did one ultrasound between those visits. Then after I talked to the heart doctor, he wrote a note to my ob saying he wants a few ultrsounds done to make sure baby is growing where she is supposed to be.
