Due date seems wrong?

Question

I got my first positive October 12th. 
I went for a scan November 12th and they said I was 6 weeks 5 days. I feel like that’s off by at least a week. I don’t have a cycle so my due date couldn’t go by a last menstrual cycle. The baby had a strong heartbeat. 
But if I calculate backwards by their estimate it means I would have ovulated October 10th... just two days before my positive test... 
Does this mean there’s something wrong with the baby...

Answer

There are so many variables here - you’re unsure of your lmp and conception date. You’ll just have to remind yourself you saw a good heartbeat and wait it out. We just don’t know and can’t tell you what’s going on.
The odds are in your favor that everything will be just fine.

Answer

Maybe I did the math wrong but I wouldn’t worry about it. My cycles are longer. They are around 36 days. We thought I was 8 weeks but was only 5 weeks 6 days at my first ultrasound because I ovulated later than she thought.

Answer

I’m confused. 6 weeks 5 days would bring you back into September. Did you mean you got your positive on Sept 10 and not October 10th?

Answer

Are you 100% certain your test was positive on the 12th and not just an evap? Sometimes people confuse a visible line as a positive but there's no pink pigment. Do you have a pic of the test when you took it?

Answer

I remember when I got told my due date was June 2019 when I didnt get a positive test till November of 2018 with my last period being in September. I knew something wasnt right because I last tested October 27th with a negative test and no faint lines. I have pcos so that causes me to ovulate later then expected. My REAL due date was July 2019.
There are definitely different factors that play into determining your due date.

Answer

They said my due date is July 2nd so I figured it out this way. But I got a positive post on October 12th so I don’t get how this is possible.
