Question is I have been eating a lot headaches feeling lazy. I have sex October 17 the day before my period I got my period October 18 then it ended 5 or 6 days later. Then lately I been feeling emotional and hungry all the time and I'm not sure why. Could I be pregnant? I read online that you could have your period of that month. I don't start my next period for 2 or so more weeks
