8-10 days late

Normally have a Regular cycle. Tender/sore boobs ( but they usually get sore a few days BEFORE period. ) this might be the first time they were sore this long. My nipples didn’t get darker or anything but I have to hold them to go down the stairs etc. frequent urination but could be because I drink too much fluids? Felt cramp like symptoms / pulling a few times the other day. Tested at 3 days late & it was negative my cycle is usually always on time so I’m excited & nervous. Should I get blood work or jus wait it out?
