period five days late

so as of today, my period is five days late. i had some cramps earlier like I usually do before it comes and my breasts were sore like they typically get about two days before I was supposed to get my period. I don't remember if my husband and I had sex, I typically log it but if we did I never logged it 😒 also today my breasts feel and look a little fuller but they don't hurt. I'm so confused by this lol so I'm reaching out to see what y'all have to say. Thank you in advance!!
