Boobs

So every month my boobs start hurting a week before I'm going to start my period. Every 3 months or so, they won't hurt. I was wondering.... Has anyone on here have the same thing and if so, did your boobs hurt when you got pregnant or not? My husband and I have been ttc for a year now and I was just curious that since its normal for my boobs to hurt every month that would they most likely hurt if I got pregnant or if there is a chance they won't hurt.
