Stress?

I've tried going slow, I've tried going fast, I've tried imagining things, I've tried teasing myself, but no matter what I cant have a good orgasm. It's so frustrating! I've been stressed out lately and I thought I might relax and play with myself (which I rarely do) but I cant really enjoy it. I dont have a partner to help and I'm currently on my period so I dont want to put anything inside because I personally find it gross, but I've done everything imaginable around thoes things yet I still cant have a good orgasm. Is this because of my stress, period, or a combination of the both? Are there anyways that I could get a good one or at least other ways I could relax?
