How many weeks are you when you are in a safe zone??this apparently says 12 weeks. My doctor said after ten weeks your chances of MC go.under 1%

I think 12 weeks is typical and your doctor is probably right about the 10 week drop for risk of MC, my doctor says 14 weeks is the start of 2nd trimester.
