Symptoms at 25wk5day

A few weeks ago my heart rate started being anywhere from 80-120. I have started feeling nauseous randomly and today I am feeling lots of pressure, back pains, and nausea all at the same time. It’s making me nervous and I can’t sleep. I am so uncomfortable, I love feeling my little one move but when it moves I feel more discomfort and tightening. Is this typical or should I contact my obgyn?
