I always feel like self harming around my period

There’s not really any reason. I can have everything going for me and still can’t fight the urge to self harm. I’m day 2 of my period. I picked a fight with my husband over the laundry and then he got mad and threatened to leave. My go to was to hurt myself. I cut my arms and I’m obsessing over the though of taking too much of my meds so I can black out...what is the matter with me? It always seems to be around my period
