trouble breathing

I'm 38 weeks pregnant and today, I've noticed that I have a lot of trouble breathing properly; lying down or standing (mostly lying). And when I eat or drink something cold, I've notice that the baby isn't moving so much like she would before. She moves but not as much as before. Haven't had any bloody show or leakage of fluid. My feet and hands are swollen too. My pubic bone feels sooo sore. Idk. I feel weird. And sad. Idk why. 😔 my next doctor appt isn't till Friday.
