12 week check-up

Last Friday I had my 12 week check up with my obgyn, only my regular doctor was on vacation so I saw someone else in the practice (I knew this when I scheduled the appointment, no big deal). I had an ultrasound before seeing the doctor, and of course I was very nervous, hoping and praying that all was okay with our baby. Of course having to drink 32 oz of water 45 minutes prior to the ultrasound and then going out into the cold help to take my mind of things a little because all I could think about was how I needed to go to the bathroom!!!!!! All is fine with our little one:) The baby measures 13 weeks and the day of the ultrasound I was 12 weeks and 4 days. The baby's heartbeat was 170- which now has me thinking girl????!! The ultrasound also did not show any signs of acrania (which is what our first baby had), and the nasal bone and skull appear to be all there- which was a huge relief for us.They did see on the ultrasound a rather large (7cm) cyst on my right ovary, which they want to keep an eye on. The ultrasound tech and doctor were surprised that I didn't feel the cyst but honestly I haven't! I just hope and pray that it doesn't get any bigger, that it shrinks/ goes away on it's own!
I had some bloodwork done, they have a new test out that they use the mother's blood and apparently they can get enough of the baby's blood from it to test for trisomy/ down syndrome etc... instead of the more invasive amniocentesis or the less accurate trimester 1/ 12 week test that they use to do. So in about two weeks we will have the results of the bloodwork (it is 99% accurate where as an amnio is 100%). With the results we can also find out the sex of the baby!!!! All I really care about is that the results come back with a healthy baby, in the end that is all that matters!!!!
I go back in 4 weeks- Jan. 31st for my next appointment and at that appointment they are going to do another ultrasound to check on the cyst on my ovary- I guess one bright spot to having it, is I get more ultrasounds:) LOL!!!! Anyone else had this same problem- cyst on your ovary when you were pregnant? Just wondering.
