PMS symptom change

[ZannahGirl1]

Hi there!
My PMS symptoms have been fairly regular for about a year now. Each month, without fail, I would have sore breasts for exactly seven days, and then once my period came, they would go away. However, things began changing in January. I did not have any breast soreness whatsoever when I expected it, but I eventually chalked it up to taking antibiotics for a UTI. My period arrived on the 25th day, around 2-4 days earlier than I was expecting it. Then, in February, I experienced greatly reduced, off-and-on breast soreness. I thought I might be pregnant (though I had no viable risk), so I took two pregnancy tests to calm myself down. My period came on the 31st day, 2-4 days late from when I was expecting it. Both months my flow was totally normal.
I am now 6-9 days away from my period and still not experiencing what was my typical breast soreness. I'm definitely not concerned about pregnancy, but I was just wondering if it's normal to have sudden symptom changes like this? I've had my period for seven years, so I would think that it'd be pretty regular by now.
Thank you for your time!

Periods do tend to regulate after the first few years, but cycles also change and shift occasionally: they will not be the same for the whole of your life. It sounds like you might just be going through a bit of a shift now, but it never hurts to check in with a healthcare provider if you're concerned.
