Is something wrong with me?

For the past few days or practically week now, I’ve found it really hard to have an orgasm. It’s not that I don’t want to or I’m not in the mood because I am, but when I’m laying down and I’m doing it, it just doesn’t seem to come unless I pay attention really hard? If that even makes sense. Or I just get turned off out of nowhere. Which defeats the purpose of me doing it for a momentary break from stress. I’ve been really stressed these past few weeks but this only started to happen after my last period ended which was on the 30th. This has never happened before and never for this long of a time… Could it be stress causing this? Please let me know
