Ahh, could I be?

So I knew my period was coming up. I'm usually the 14, 15, or 16 when I start. Well I haven't really had any signs of starting my period other than bloating. I have been working out for a couple weeks now so I'm sure that has messed with it. My sex drive has been up more than normal around this time of month. Getting excited but should I test tomorrow or wait a few days?
