I'm a week and two days past when I got off of my period. However I'm starting to feel way way waaaay exhausted, my nipples itch and then they are SO sore after, my back hurts, I have some nausea here and there, my appetite has increased, If I smell certain food I get SO sick to my stomach, & not to mention, my stomach kills me here and there along with some dirrhea. I don't think it's possible to have ALL of those symptoms THIS early if I am pregnant.  What should I do? Could I possibly be pregnant? AF isn't supposed to be here until Aug 31st.
