Okay to make this post short and sweet

So I was supposed to start my period on the 27th. But instead I was greeted with spotting 3 days prior. So yesterday I believe I stopped spotting. But throughout 2 of those days, I had light bleeding. Nothing to fill a pad, should I wait to test? If so, how long? I’ve been feeling nauseous, having trouble sleeping. I’ve been eating like crazy 🤨 but certain things make me feel like I’m going to get sick while I eat, so I throw the rest of it out. Any advice?
