Help I’m late

I’m currently 3 days late on my period and I don’t know why, last time I had sex it was protected. I recently took a pregnancy test because I was paranoid and it said negative, I’ve been working out daily for only 3 days but I had stop because I thought that was the cause of my period being late, I still don’t know, usually be on time. now I have period symptoms like acne and discharge and slight cramps, do you think it’s coming soon and I’m overreacting?? Also does anyone have tips to make it come faster right
