Quick answer
Do I make up fasts missed during menstruation?
Yes. Fasts missed for ḥayḍ or nifās during Ramadan must be made up (qaḍāʾ) later — ideally before the next Ramadan. Prayers missed during menstruation are not made up; only fasts.
Yes. Days of Ramadan missed because of ḥayḍ (menstruation) or nifās (postpartum bleeding) must be made up (qaḍāʾ). This is the consensus of the four Sunni madhhabs, based on the words of ʿĀʾishah (raḍiyallāhu ʿanhā): 'We used to be ordered to make up the fast and we were not ordered to make up the prayer.' (Sahih Muslim)
The make-up fasts do not need to be consecutive. You may fast them on separate days whenever you are able, as long as they are completed before the next Ramadan begins. The Jumhūr (majority) consider it disliked to delay qaḍāʾ without excuse past the following Ramadan.
If a valid excuse (such as continued illness, pregnancy, or breastfeeding) prevents you from making up the fasts before the next Ramadan, you make them up afterward when you are able. Schools differ on whether a fidyah (feeding a poor person) is also owed for the delay — the Hanafi school requires only qaḍāʾ; the Shafiʿi, Maliki, and Hanbali schools add a fidyah for delaying without excuse.
Counting missed days accurately across a whole month is where many women lose track. Noor records each day skipped for ḥayḍ or nifās during Ramadan and keeps a running qaḍāʾ total, so you always know how many fasts remain.
This summary draws on the established positions of the four Sunni madhhabs. For your specific situation, consult a qualified scholar.
