So my LMP was July 22 and according to that I should be 9 weeks tomorrow but I went and had my first untrasound today and baby is measuring at 6 weeks. Heart rate was good they said but I'm really confused how that works. I had a miscarriage in May and I'm freaking out because I lost the last one at 6 weeks so I'm terrified that I'm going to lose this one too. Has anyone ever had that happen before where baby measured 3 weeks behind?

Update: Dr got my blood test results in and my progestrone levels are lower than they want theyre putting me on some medication until 13 weeks. If yall could pray or whatever you do please y'all. I'm freaking out I dont know if my body can handle another miscarriage it almost killed me in May.
