Ultrasound Confusion

Jessica
Hi everyone! I am a first time mom and I had a quick question. This is my first pregnancy and of course I want to see my baby every chance I can get. I received my first ultrasound at my first OBGYN appointment which was at 8 weeks. I had my 2nd appointment at 12 weeks and no ultrasound. I was surprised! I asked my doctor how come I wasn't getting an ultrasound she told me I won't get another one until I am 20 WEEKS!!!! I feel like that is ridiculous! Does everyone's OBGYN do that or just mine? It's crazy I can't see my baby again for another 3 months!! What should I do?
