Should I go to the doctor

My period this month was only a few hours and that it , last month it came but went away due to me and bae had sex while I was on it. This month I start bleeding a little bit and it only lasted a few hours and was done. Been throwing up and extra hungry and tried. I took a test and it was negative. Should I make an appointment with my doctor for blood work. Am not stressed out about anything. Like my period has never lasted a few hours and that it
