TWW weird symptoms

So I am in my 2 week wait (a week to go!) and I'm having the weirdest symptoms!!! Earlier this week I was really nauseous 24/7 for 3 days, now the nausea is gone for the most part and now for the last 2 days I've had the worst migraine! I also am both starving and feel full 100% of the time, and I'm having horrible mood swings. With my first pregnancy the nausea never went away, my boobs were SO sore it was crazy and I was just ravenous all the time. I know that every pregnancy is different but are my symptoms anything close to something that could possibly be pregnancy? UGH!
