Has anybody had blood work done to find out the gender and was it wrong when they did the ultrasound? I’m supposed to be having a (GIRL)but my mom thinks it’s a boy bcuz I’m low whatever that means lol

Update I’m having a GIRL thank you guys but the lady said I’m measuring at 18 weeks and 1 day and my ob told us we was 19 weeks and 1 day so idk who to believe but I’m happy everything okay I don’t see my ob until next week but she wants me to come back in 2 weeks. Thanks again everyone 😙😙
