boob pain

Sa
Anyone have helpful remedies or tips to ease the pain?! I already have huge boobs (38G when not preg)  and I am only 5 weeks preg but I have had crazy boob pain for over a week. I have one bra that feels ok on but then it hurts my shoulders after I leave it on too long. Is there anything I can do or eat to help??! 
I am 33 and this is my first pregnancy, we have been trying for 2 yrs.
