The wait is killing me

So I posted before about some symptoms I had been having, I have had a lot of fatigue and headaches daily as well as some aversion to foods like sausage cooking, so two days ago I had serious cramping like I was going to start my period but nothing ever came and now the cramping is gone and this morning I woke up with horrible nausea I probably could have easily thrown up but I refuse, the nausea continued throughout the day and the only thing that made it subside was eating. My mother who knows we have been trying pressured me into take a pregnancy test yesterday even tho I'm sure it is to early to take one. Any thoughts, could I be pregnant?
