opinions I gues

I hate turning to you guys but I feel as if you guys understand. As I have previously posted I am trying to conceive. I have a 33 day cycle. I have 10 days until my period is due, I am unsure (but have a really good idea) when I ovulated. Well today I am extremely tired, I'm super nauseas, I'm craving pickles and spaghetti, and cinnamon twists. I have been peeing a lot more since Monday. I get a headache every day since about Sunday. I feel somewhat bloated and just not myself. I a also dizzy ever so slightly, almost like I'm not drinking enough water but I am consistently drinking it. I am not stressed out. Anything would be greatly appreciated. Is this in my head or what???
