Hello, I ve never been on this before so bare with me. I am going onto day 4 with out my period, my period is never late, and when I am stressed it doesn t become irregular, I ve been getting stomach pains on and off for the past 2 weeks, my stomach has become bloated looking. I feel nausea but haven t become sick. And I m not sure what to do, or if I am worrying too much, and it has been about a month since any sexual activity, I am not on any birth control,
