Can I be pregnant?

Latasha
May 7-11 I spotted for 5days and then a week later I slightly bleed heavy for 1 day and then it got lighter until I was just spotting again. It is now june 8th and my period hasnt started yet. I have been very tired and sleepy. I am nauseous and have head aches. I have also had some mild like pain in my stomach. Any advice will help. Thanks
