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

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

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

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

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

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

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

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