boobies hurt

so this is the 2nd week where my boobs hurt. only when i squeeze them or pat them. it feels like sore muscles pain. but when i dont touch them they dont hurt. their form is alright no weird pimples. both look the same. nothing weirx im my armpits. idk if it s just bcz i gain more weight recently and the boobs are a bit bigger and heavier than few years ago. or the hormones with period next week. but usually it s during the week before period. not two weeks before it. any advices?

ofc if it lasts longer im planning to check with a doctor. but just wondering what it might be
