Is it normal for your breasts to get harder before your period? Saline implants

I got 550 saline implants one in which I have grade two cc . It has always been somewhat hard but still looks natural I am 6 months post op and I notice it feels a little harder than before could it be getting worst it can it be because I am starting my period my other boob also feels a little harder than before but the one with cc I can tell is harder than before I noticed it had cc 1 month post op . Should I have surgery to remove scar tissue even tho it looks good ?
