For the past few weeks I have been really nauseated and vomited on three occasions with the last time being Saturday evening. I have irregular periods and have never been pregnant. My period started on Friday July 4 and has been really heavy. I think the nausea and vomiting was because of my period but then someone mentioned to me that you can still have a period and be pregnant.

Could I have been vomiting because of my period or is there a chance I might be pregnant even with a heavy period?

I would go and consult with your doctor and then you will get all of your answers!
