My left boob has been aching ever since I found out I was PG. Now, the left one has stopped aching and I'm getting pains in the right one. Normal?

In all honesty "almost" any kind of ache is normal in pregnancy. Everyone's body is different and as you know, sore breast are common.

I agree with Mango, its probably normal. We get so many aches and pains

I get a lot of aches in my boobs. Sometimes its consistently in one and then it will switch to the other or be in both. A lot of times I leak a little after it has been aching. I wouldnt worry about it.
