My hcg levels and fetel measurements say less than 5 weeks?
Did your doctor discuss the possibility that you've had a blighted ovum (early miscarriage)? If you've known you were pregnant for more than a couple weeks, it doesn't sound like you were just late ovulating and this is a viable pregnancy. What tests are scheduled next?
Best wishes. I had two blighted ova and 3 healthy babies - it's hard.
If you never got a positive until after Nov. 5, it seems more hopeful you just aren't very far along. If you had gotten strong positives at the end of September this would be much more concerning.
You may have skipped a period and are just now 5 weeks pregnant. LMP dating of a pregnancy is often very inaccurate for just that reason - and if you don't have a + pregnancy test matching the LMP you really can't trust the LMP.
I think you'll be able to know a lot more next Thursday. Best wishes.
