Weird Period…?!

My last period ended about 2-3 days earlier than normal, that was a month ago my current period was supposed to start 9 days ago. It’s never super accurate but at least within 2-3 days of when eve predicts it to be. I’ve taken 2 pregnancy tests one 5 days after being late, and the other 7 days after being late both were negative (I have crazy anxiety just wanted to make sure lol). Should I go to the doctor or am I over reacting? I’m pretty regular (within 2-3 days) so i’m a little worried. I’m probably going to take another test tomorrow just incase but i’m starting to get worried about my health tbh. Help plz 🫠
