Boobs feeling like they stopped hurting

Hi ladies I'm 7 weeks tomorrow. and my boobs have just stopped hurting as they was I don't know if this is cause I've high pain threshold and now just used to it or if it's something that happens. This is my first pregnancy and have no idea what to expect. Had no other symptoms, so maybe it's normal who knows ? Can anyone help she'd some light on it?
