When did you go into labor if you have fraternal twins?

Sorry for the double post— my Dr told me she wants me to go to 38 weeks because I’m pregnant with di/di twins (I think?) they each have their own placenta and sac. Boy / girl. Is it usually pretty common to make it to the full 38 weeks or when/how did you mommas who had the same type of twins deliver? Thank you in advance
