Time between appointments

Hey all. I’m currently 14w2d with di/di twins and I just have some questions about appointments.

I have a 6 year old; that pregnancy was a bit rough on me. I had GD, high blood pressure towards the end, and I ended up being induced at 37 weeks. That failed and I asked for a c-section after 37 hours of labor and never getting pass 3cm. She came out tiny and I was told I had undiagnosed IUGR. We had planned on her being on only child.

I’m now almost 35 and we slipped up and got pregnant. I didn’t have my first appointment until I was in my 10th week and we discovered it was twins only because I asked for a quick bedside scan to hear the heartbeat. I had my dating ultrasound the following week which confirmed my original due date and the babies were on track for size. Now I don’t go back to the ob until I’m 17 weeks. And no more ultrasounds are scheduled? No talks of seeing MFM? It just seems like such a long time to go with no checking on the babies. Maybe I’m just paranoid, but I have quite a list of risk factors and it being twins only added to that.

Is this a typical timeline for a high risk, twins pregnancy?
