I Had My Period The 2nd Of April And It

I had my period the 2nd of April and it finished 6 April and the next day I went to a Mexican restaurant and I then went to a pet store with my crutches.. (Fractured. Ankle) I felt really nauseous I wanted to faint and did faint.I've also had some random headaches and I have been feeling very tired lately? Is there a chance of me being pregnant? Or is there something else going on? Im very healthy
