NIght sweats, excessive eating and over sleeping? Pregnant?

I know I just need to take a test, but I just want some other opinions. I am 22 years old and I just had my daughter six and a half months ago and my body has snapped back perfectly and I am in perfectly good health. I have been back on the pill for about 4 months now and well I haven't been steady with taking it this month. I forget to take it at the same time every day or I double up the next morning, which I know I probably shouldn't do. So I have noticed I have been feeling very gassy, lots of heartburn, waking up drenched in sweat, sleeping all morning except to get up with my daughter and The I go straight back to bed. I have been eating non stop!! I have been slamming hot dogs left and right and I never eat hot dogs and I am obsessed with Jalapenos suddenly! Not to mention I hate eating bone in wings and I slammed a thing of 12 at dinner two nights ago. Has anyone had the same symptoms when they were first pregnant? THis is completely different then my first pregnancy and I am not sick as a dog this time either. Again I know i need to see my doctor and get a test but I just want to know if anyone else had experienced the same thing during their pregnancy. or if you have any other ideas as to what it could be? THANKS!!!
