How far along am I?

L🎀 • N

Some websites to count when the first day of your period was and some say to count from when I conceived...

My first day of my last period was the 1st of jan (meaning I’m due Oct 8 and i would be 6 weeks and 2 days today)

Or the day I conceived.. well I got a positive OPK on the 23rd jan (meaning I’m due Oct 16th and I would be 5 weeks 1 day today)

Which one am I?? So confused!
