Could I be pregnant???!

Kayla
So before April my period was down to a science. I was supposed to start my period April 25th.... and didn't. So I decided to give it a week and still nothing. Here it is May 14th and I still haven't had my period. My next period is scheduled to start 9 days from now........ I took a few home pregnancy test, which all came back negative. In the past two weeks I've felt cramps, but no such luck with starting. I've also, in the past few days started to get really annoying pain in my upper abdomen, almost like heart burn. A few days ago and this morning the pain woke me up and I've physically gotten sick twice, once on an empty stomach..... I have an appointment this Tuesday, and besides my period not starting, should I tell my doctor everything else my body has been doing? Or are they even relevant?
