So uncomfortable

I’m a first time mom and everyone that has gotten pregnant around me made it seem so easy and not painful or uncomfortable. But my god there is always pressure on my pelvis and it makes me so sore I’m always uncomfortable and in pain and I don’t get how well I’ll take the next 15 weeks that I have left. My tummy is getting bigger by the day and just makes it 10 times worst. Please any advice to help.
