Period Talk

Has this happened to anyone? So last month I had no period at all . I faced some super stressful things as well as dealing with my regular anxiety. I took lots of tests and all were negative. I now just got my period the same day I was supposed to get it last month . Which is just weird to me like it just straight up skipped a whole month. I know it was probably because of the stressors I faced . And so far this periods pretty normal really strong cramps and flow on the first day they are just lasting a little longer. I know I should get a doctor and figure out why my period isn’t regular. But I’m just confused this hast happened to me in so long and should I be worried about worse symptoms or pain since I missed a period?
