I don't know what's happening to my body.

So I use to not get under arm odor and now I swear I smell all the time no matter if I shower or use deodorant all the time. I also feel more hungry in the mornings than normal.

I've googled all this and some pregnancy things come up, I'm scared Im just now moving out of my parents and starting my life with my husband. We are not ready to be parents just yet.

Also I'm on birth control and not the greatest at taking it on time could that be something? Also just had my period on time last month. I took about 3 tests and they all come out negative. Anyone have any advice or know what's going on?
