Diagnosed with short cord & Placenta lake?

I am 21 weeks I’ve had a very large hematoma up to 12 weeks then at my 20 week ultrasound they said that the hematoma is gone now. I guess now I have placenta lake short cord and my placenta is placed in the wrong spot they said that the baby is measuring perfect right now but as the pregnancy goes on the baby could be very small I’ve had two children previously and I had them both early. My first child what is the emergency C-section my second child was a Vbac and now they said I’m going to have to have a C-section and I’m going to see a high-risk doctor. just looking for some advice or other stories like this to help me stay positive.
