I just read one of your previous posts. I went through someone similar. I went to the dr like 3 times and all they saw was a sac. I went back again about a week letter and they saw baby and hb. I was measuring a week behind. Try not to stress. I’m sure everything is fine.
As long as your numbers double every 48 hours there isn’t concern. There’s such a wide range of what’s acceptable for how many weeks you are. I know a lot of drs don’t even use the chart they just want to see it double.
1,061 with my last pregnancy at exactly 5 weeks. With our second son I was over 2,500 at 5 weeks. It's amazing how much it can vary from pregnancy to pregnancy.
