WHEN IS THE 2ND TRIMESTER!?

Sh

Okay so I'm getting really confused and I just want to know!! 😣 I've seen some people say it's 12 weeks, others say 13 weeks then some say it's 14 weeks! But this app is telling me I'm in my second trimester since I've hit 12 weeks? I'm 13 weeks tomorrow, so yeah.. help? 😂 thank you x
