Aunt Flo question

Jamie
I know this sounds silly but I been TTC for a long time now. Just moved and hoping to get established with new doctor soon. But anyways my question is when you have your period is the blood usually brown because your sheding old blood?  I been getting my period like every 2 weeks and it's fresh red blood and lots of blood clots. Should I be concerned or this normal. Sorry if I put this in wrong category area but have no idea where to post this. I look forward to answers.
