Am experiencing really, really sore breasts for last couple of days. I am not breast feeding, don't think I'm pg. I am due my period in the next few days and I do often have heavy sore breasts, but not like this. I'm only a 34B so fortunately they're not very big, but they're really hurting even when i'm sitting still, they also feel really firm. I don't remember my breasts being this painful in previous pg. Anyone got any suggestions, my sister has suggested putting frozen peas on, sounds very cold with very hard nipples. Not looking forward to lying down, even though I'm wearing a support vest thing.
