3 days late

Savannah

I’m currently 3 days late, I’ve had sore boobs, cramping and really watery discharge, this has been going on for at least a week which is abnormally long for me. The last few days I’ve had some insomnia between not being able to get to sleep, needing to go to the toilet in the middle of the night of just waking up through the night. I don’t know if my period is just a little late so I don’t know if I should test yet. Has anyone had this?
