currently 10w5d. my pregnancy app tells me I'll be in my second trimester at 12w, how accurate is this?

my doctor and I go by this, second trimester would start at 14 weeks.

I haven't really asked my Dr and my next appointment isn't until march. but this app goes like this

very accurate my doctor wrote these for me@dee21 both my high risk and ob go by this

because they say the 9mths are supposed to be split up in 3's.. so confusing lol

I guess I'll have to ask my Dr. because everyone I've asked has different answers lol what if I'm not going the full 40wks because I'm having a csection? @hermommy

it's still that lol evryones pregnancy is 40 weeks most just don't make it to that, I'm mostlikly also having a Csection @dee21

Wow I'm glad y'all explained this I'm 11weeks so at 14 weeks in my mind I'm thinking that made 3 months lol
