I feel lost

Hey everybody! I am current 9 weeks pregnant today but I just recent saw my OB at 8 weeks 6 days but she says baby is measuring 5 weeks 6 days? So I was very confused how I found out I was pregnant over a month ago even with a positive digital test and I'm only 5 weeks 6 days (when I saw my OB) so of course I'm nervous and I Google it. Turns out lots of women have had the same issue as me and their baby had just stopped growing at 5 weeks and they eventually lost it or the doctors basically had to force a miscarriage. I've had 2 miscarriages in the past and I am so worried 😔😔 we have tried and prayed for this baby. I go back to my OB in 2 weeks for another ultrasound and I really hope everything is okay. Has anyone else been through something similar and had a good outcome??
