I just go by the word. so tri means 3. theres three trimesters and you go through three months each for the trimester. so 1-3 first. 4-6 second. 7-9 third. and there's 4 weeks in a month. but I just think weird. I got tired of different charts all the time so I just broke it down in a way I could understand better.

I don't believe everything I read on the internet is true but I was confused lol. i go to the Dr. on Wednesday and I'll see what she says. I just wanted opinions from other mommas

13wks is your 2nd trimester (this is my 7th baby) all my doctor say is 13wks

depends on what website you're reading from. haha. I've heard both too, but most I read from says 14 is the 2nd trimester.

Your still in your 1st when you turn 14 weeks thats your 2nd congrads @bat_girl96

I thought so but I wasn't for sure thank you @gr8mommy2b
