Officially weirded out

Ok so I need some help figuring this out. My cycles are usually 32 days. I normally O on or around CD 20, give or take a day or 2.  Usually, from about 1 dpo, until AF shows, I get really sore boobs. I am currently on cd 25 (5 dpo), and my boobs are not sore anymore. Can anyone tell me what this may mean? Anybody going through this?
