What week starts the 3rd month of pregnancy 12? Or 13 weeks?

@mommy4ever.more, Oh so I'm already in my 3rd month.

@laquitax2 If you go by the chart, yes, but some people do it different. With all my pregnancies I've done it this way

@mommy4ever.more, Yeah it's the same as the one I used with my daughter.

@laquitax2 I have that one too, I think I have like 4 of them lol and they are all the same
