Scheduled C-Section

So I am 28w1d with mono/di twin boys. My OBGYN and MFM specialist have both stated that they aren't going to let me go past 36weeks. My original due date was 9/12They both also stated that c-section is the common mode of delivery for mono/di twins. Which is fine with me..I really don't mind. Just overall want a healthy delivery. We have not scheduled a c-section date yet. Is it still too early? Are there any twin moms out there that already know their date for c-section?
