Thoughts please???

I had my period a week ago, had unprotected sex everyday.. The last few days I've been feeling very different in my body. Always hungry, nauseous when I wake up, soon as I open my eyes I'm so dizzy. I know it's way to early buy I feel so different. I'm also on the pill but I don't take it at the same time. I just feel so different. What are y'all thoughts? Once again I know it's so early but I think we all know when something wrong with our body.
