I’ll be 12 weeks tomorrow and I’m super ready to know the gender. My doctors told me I don’t get another ultrasound and know the gender till I’m 20 weeks. I don’t think a can wait that long I’m so impatient lol. My next appointment is on the 8th is there any blood work I can ask them to do?? So I can finally know what my ❤️ is. Also this is my first pregnancy really excited and nervous
