extended cycle...

So I've been to the doctor already and she doesn't seem concerned. I am now on my 23 day of having my period. In less than 30 min I will be on day 24.

It started last month. I was late so I was hoping to be pregnant. I was 15 days late. pregnancy test said no. Blood pregnancy test said no. That was on the 26th of last month. on the 30th my period came. With a vengeance.

Now here we are... and it's still here....

My doctor did a pap. (Not a very comfortable situation) sent me for blood work (cause I'm not losing enough right?) then sent me in for a internal & external ultrasound. I am still waiting for the results.. is this normal? Or should I be worried?
