BUT, this is a personal decision that you should really make on your own. Being as young as you are, you may feel like this is something that you need to do- and that is perfectly fine.
If you do go, I can tell you that they will either tell you to go home and take it easy until you recover, or they may want you to have a D & C.: An outpatient procedure where they most times- put you under for couple of hours and "scrape" your uterus to ensure that no tissue is left behind. Sometimes, they may perform the procedure in the office while your fully awake (but numbed) depending on your doctor's decision.
YOU SHOULD DEFINETLY GO IF, like I said, your bleeding is still very heavy (it's been more than 3 days, if my calculations are right) and the pain is still the same (or worse), and/or your running a fever. Then, you should go to your lady doctor (or emergency room) right away.
AND, If it will ease your mind to see your doctor (if you are still worried about your health); then yes, by all means go, there is no sense in making yourself worry any more than you have been. Miscarriages are emotional enough, no need to add anymore worry to it!
AND, you don't have to make this your last question, like I said, I'm here if you have ANY questions- no matter what you decide to do! (I've experienced both D&C methods and I have miscarried without seeing my doctor, so I can relate to how your feeling!)
