No, it doesn’t but you must not swallow the blood.

I wanted to when I brush my teeth I see some bleeding from my gums , does it breaks the fast during the Ramadan?

I wanted to know that if I fast the 6 days of Shawaal, can those be counted as the fasts I miss during Ramadan due to periods. Or do I have to fast those 6 and then make up all the ones I had to leave during Ramadan?

(1) If someone is unable to fast due to medical reason he will always give fidya (2) If someone is unable to fast due to some temporary illness or travelling he can do Qaza of the fasts or give fidya (then Qaza is not required)
