Strange sore/tingly bbs

Know this is a bit random but normally i get sore bbs a few days before period but for some reason I've had this for over a month. The period before last came 9 days earlier than my expected start day which is always 28 days. And was only spotting for 2 days. Then I started what seems like a period another 24 days later which only lasted 2 days but was a bit heavier this time. All through this I've noticed my bbs have been getting bigger and last night my husband commented on them, today I noticed my nipples have gone really dark and are really tingly again. This is so odd normally I only get this when I'm pregnant, but I took a test and it was negative. Anyone else had anything like this? I'm only 35 hoping it's not perimenopause?!
