Hi, I don't know what to do, found a lump in my breast last night but I was day 1 period so it could just be that? It's hard and behind the top of my nipple, still there this morning. Asked my husband to feel it but he wouldn't, said to get doctor to look at it. Should I just see if it's still there after my period has finished? I'm mid 40s and think staring hormonal changes, maybe perimenopausal so I gues it could be tied up with that. Don't want to waste anyone's time
