Google pregnancy weeks to months conversion chart, its not 4 weeks a month, thats not accurate.
It says I'm 8.2 months. I'm 36 weeks 2 days.

If you google "pregnancy weeks" there will be websites that have charts on them. It really depends on how you want to count. You can count by every 4 weeks. That's how I've been doing it or you can use this chart. .
I would say it's more like 4 to 4 1/2 months. A full term pregnancy is considered 40 weeks. You're more than half way. Sorry I don't have a chart.
