Anyone less pregnant than they thought?

Jennifer

According my my LMP I’m 6 weeks along. My hcg levels are rising (in the 7,000s), my progesterone is good too. Had my sonogram today but all we can see is the yolk sac. I NEVER get my period regularly (LMP 12/1) so I have a feeling I ovulated later. I think I’m less pregnant than 6 weeks. I feel peace in my heart that everything is ok. Anyone else have a past experience like this?
