@sandraluvx thank you luv also dont listen and go by the Google charts there very wrong. Ive been in 2 states with different Obgyns and both offices say there wrong go by whats always been correct for centuries. For 21yrs its been the same since I learned I was pregnant 22wks is definitely not the start of the 6th month because anything under 24wks is considered miscarriage over 24wks (6m) is stillborn I've been through it so I know what I was told
4-12 if 1st trimester
13-27 is 2nd trimester
28-40+ is 3rd trimester
