I always get really sore boobs at the beginning of pregnancy. But by 8 weeks it's usually worn off.
I know that if I wear underwired bras all day they absolutely kill when I take it off. And also if I don't wear a sleepbra to bed, they really ache in the morning.. kind of like what you're describing. They need to be supported pretty much all the time in pregnancy, as they are gettin ready to produce milk and are getting bigger.
Hope it ease soon
