Hot and Hungry....Pregnant or Period?

Lately I have been hungry and very hot all the time, which for me is different. I'm so used to being cold all the time. It's hard not to get my hopes up when I have these "symptoms" especially since both pregnancies (I miscarried in January at 5 weeks 4days) I felt the same way. It's also confusing to me because almost every time my period is coming I also get hot and hungry!!! Go figure, huh? Oh well, we will know for sure on Thursday! It's going to be a long couple days.
