Waiting...

So I'm 9 dpo and period is expected this next week. I will randomly feel nauseous but it only lasts a few minutes at most. I also keep waking up with slight cramping and feel SUPER bloated, along with being incredibly tired all the time. I don't normally feel this way before a period, and even the cramping usually doesn't start up until a day or so before. I'm going to just wait and see if my period comes before I test but I'm curious if anyone knows if this could be it?
