Pregnant with a period?

For the last 3-4 periods they have only lasted about 3 days. The first day being fairly normal flow, a super heavy day and kinda heavy then poof done! My normal period lasts 5-6 days. I have been sooo tired. I get 8 or more hours of sleep and i am so tired i can barely keep my eyes open. If I don't eat within like 10 minutes of getting up I feel like i am going to starve to death. Sometimes i get so hungry i could eat a whole pizza. Last night I ate all but three pieces of a pizza hut pizza mia pizza and i still didn't feel full, but stopped there. Pants are getting tighter and i keep feeling little flutters in my stomach. I have even been going through these like week long crocheting fits. In one day I crocheted 3 hats. I have ordered some pregnancy tests (online they are ones i have used for yrs) and will take a couple when i get them in the mail. Has anyone else experienced this before after having two pregnancies with no periods or even one? I know every pregnancy is different, but this is crazy different. My first two kids i felt sick for months all day long. So far with all this weird stuff happening if i am pregnant it is very different. I also had a week or more where i felt sick after i ate. When i didn't eat on time i felt dizzy and spacey. Aside from taking a test to find out any advice or suggestions?
