Just wondering if someone could help me understand what's going on. I'm 15 weeks pregnant. I was admitted to hospital last Friday with bad chest pain. My blood gasses are low, my D'dimer is high 0.9 reading and my echo came back with a slightly high pressure in the right ventricle 30-40. I had to have a vq scan for a suspected blood clot but it came back clear.

Im not sure of all these medical readings and wondering should I be worried?
