Am I just overthinking it ?

Hey guys ! Recently married here and my husband and I have stopped using protection. Wow I can’t believe what I was missing out on! Anyways. My cycle is like clockwork and I am supposed to start my period today… it always starts in the morning. Should I take a test ? I haven’t been sleeping well and have gotten like hot flashes which I know period also does that. Also was nauseous several days.. I know I am probably overthinking it but what should I do? I would love a child but definitely planning it lol. My cycle is below for info. No cramps, my boobs don’t hurt or anything.
