Need help- TMI photo

Melissa

My LMP was 11/15, ovulated/conceived 12/4 or 12/5, positive test 12/18. Period due 12/18.

EDD 8/22 I should be 8 weeks 2 days today. My sonogram is showing I am 6 weeks 3 days.

Either one of two options I ovulated later and am not as far along or 2- the baby stopped growing and will miscarry soon.

Anyone else been in this position and had a good outcome?
