Almost 2 week long period....

Hello!  I had a chemical pregnancy in November and another in December so I haven't had a normal period since September.  I started bleeding and cramping (like a normal period) on Saturday (2/27) and there were quite a few clots, which I read is normal.  I had a normal period through the following Thursday and Friday and then I had light spotting of dark brown blood, which again is normal for the end of my period.  But Monday the spotting got a little heavier and then yesterday was a full blown period again complete with cramps and normal first or second day period bleeding.  I had some clots too.  I'm just concerned because it will be two weeks this coming Saturday and I have a scheduled OB/GYN appointment on Friday morning.  I am glad I have the appointment because we will be able to discuss this long "period" but I can't get a Pap Smear since I am due for one, can I?  Any one else have experience with awful periods after a miscarriage?  Am I freaking out over nothing?  I know I'll get through it and it will be ok but I have been waiting to TTC again since Christmas without a period and we're ready to try again....  My doctor feels that he knows the reasons behind the mc's and feels like the next one should be succussful because I will be taking progesterone with it and I'm still young but I'm just getting anxious I suppose.
