How far along am I?

Question

I know the first day of my last period and the day in which I ovulated, which one do I go by? If I go by my last period I am 5 weeks 2 days. If I go by my ovulation date I am 3 weeks and 5 days.. which one do I go by??
Edit- LMP first date was nov 23. Ovulation positive was dec 16th. So I’m assuming conception/ actual ovulation date is dec 18th. So they’re quite far apart. I don’t have the normal 28 day cycle

Answer

I would go by conception. That's a big gap. Dr may opt to use LMP until they do a dating ultrasound, then adjust accordingly.

Answer

You go by the first day of your last period

Answer

Doctors and ob’s go by the day of your last period. Even though you think you know the day of ovulation implantation can happen over a number of days so it’s hard to pin point an actual day.

Answer

Even if you didn’t have a period they’ll add days to pretend you did. I know exactly when I conceived but didn’t have a period before because I’m breastfeeding. But the docs have all been like “okay we will just say your last period started 1 October for dating purposes”

Answer

First day of your last period!
