I had inprotected sex the day right after my period ended but he pulled out. Its only been a couple weeks now but I've felt dizzy and kind of nauseated though I have not thrown up. I've had a couple headaches and now I am feeling unbearable hunger no matter how much I eat I still feel hungry. My breast also have been sore & I have bumps around my nipples? I'm not sure if all this is just a coincidence but can it be early pregnancy symptoms? Its too early for me to take a test.
