Black menstrual cycle, help

Hello hope all is well.

About 2 weeks ago my boobs have hurt to bad so i figured i was going to have a period. About a week ago i thought i was starting my period for the first time since January and i had like just one black blood clot come out on that monday.. so hit and miss never needed a tampon but i can see when i wiped the black discharge. during the week it was just some dark black discharge, then Thursday was a little pink discharge and then that Sunday it was over. My boobs have been super tender and i was curious if this is normal. Ive gone over a year before without a period and never had this happen before.. help
