Nipples and boobs burn

I’m due July 14th! 2018 and my boobs burn when I’m outside in the cold ( I live in Northern Ontario) and my nipples leak so much to the point of me screaming when they are touched, my boobs feel so full and heavy and I can’t find any relief ..

other then that my next ultrasound is on the 31st of jan and I just wanna know that my baby’s still alive and well cause my boobs are the only symptom and that and some butthole pain lmao

Help
