Could I be pregnant again?

I know I just need to take a test, but Im honestly scared to take one. I just had my daughter six and a half months ago and my husband and I wanted to wait a couple years until we tried for our second. 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, bloated, lots of heartburn and 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? I was always hungry with my first pregnancy but I just couldn't eat a lot because nothing sounded good. I was sick as a dog for my first trimester. So if i am things are very different this time! Again I know i need to see my doctor and get a test but I just want to know if anyone else had the same thing in their pregnancy. THANKS!!!
