😳😳😳 Anxious

So my SO and I have been ttc for 2+ years and no luck so far. It's been a very trying time and staying optimistic is key. But lately I've been so tied, my body has been tingling all over and I just have this weird feeling. We've been BDing so much this past month and my last period only lasted 4 days which NEVER happens (irregular cycle) so I'm anxious to take a test but goodness I don't want another negative smh I am my worst enemy on this one lol should I test?
