Sought out an ultrasound tech!

So I just found out I'm pregnant on valentines day and my last peruod was the last week of december. I have PCOS though so it's hard. To go by my periods. I don't know how far along I am and want to know right so I started making my first doctors appointment and it's Monday but my sister said that they won't even do an ultrasound for like a month or 2 and I don't want to wait that long! So I'm going to an independent ultrasound place and they are charging me $50 plus I get to walk away knowing how far along my baby is and 2 pictures! I'm so excited!
