Need some advice on high risk pregnancy!

Champlin • Mommy to a 3 yo prince and due 04/22/18 with a little princess ✨❤

Today I was seen by my obgyn who told me I am considered high risk since my last pregnancy ended at 31 weeks due to pre-term labor so I go see high risk doctor on Nov-3, and they already want to do an ultrasound. They also want to start progesterone shots every week. I'm wondering how often I will be seen at the high risk doctor based off any others experience who's considered high risk.
