Induction scheduled-Freaking out!

Krystina • Married 6/28/14; Thea Quinn 5/3/16; Jace David due 9/27/17
Cervix was checked this past Monday and I'm 0 cm dialated! Nothing going on down there lol. I'm 39 weeks tomorrow, but because I've had some heart issues and my pressure is going up doc wants to induce me this coming Monday night. I'm starting to freak out as I'm a FTM and even though I did a lot of research I still have no idea what to really expect...any tips?!
