Question Summary:
I was keeping a qadhaa roza and at about 11am I got my period, subsequently I broke my fast, do I have to keep qadhaa of this qadhaa? (I had 6 qadhaa rozas before I started keeping this one, so will I now have six or seven?)

In the name of Allah, Most Gracious, Most Merciful

Assalaamu `alaykum waRahmatullahi Wabarakatuh
 
Since a Qadha fast is only a substitute for the original, you would have to only  make one Qadha i.e. there will still be six fasts compulsory on you; not seven.
 
حاشية ابن عابدين - (2 / 560 سعيد)
وقد وجد العلامة الشيخ إسماعيل النابلسي هذه المسألة منقولة فقال ولفظ المبتغى لو فاته الحج ثم حج من قابل يريد قضاء تلك الحجة فأفسد حجه لم يكن عليه إلا قضاء حجة واحدة كما لو أفسد قضاء صوم رمضان اه
