Various sources indicate that overnight fasting needs to be from 8 to 12 hours. It is obviously important to reach the minimum, but also to not exceed 16 hours as this can yield unreliable results.

I am faced with a similar situation. I need to fast 14 hours before my blood work, and I would like some iced tea. I have only been fasting for 4 hours, so I still have 10 hours to go.

Should you fast or not coz your menses are back after one year of giving birth in the month of Ramadan but the sign of blood is undetectable?
Basically, women can't do fasting in Ramadhan month where they are in monthly period (menstruation) OR after maternity period. We know Al Qur'an said that women monthly blood are dirty thing which burden women worship. When the blood REALLY come out (means that you can see the red stripe on the 1st day) then you have to stop praying and can't do fasting for 10 days long until the blood stop. But, if the blood doesn't stop for more than 10 days then you have to start praying and fasting as you have to check your condition to the right doctor to avoid any health problem inside your body. Same with women in maternity period. If the blood still come out then you don't have to pray and fasting the whole month until the blood really stop. The conclusion is, keep fasting as long as no blood come out from your sex. Even if you pregnant and you think u might able to fasting without burden your baby's nutrient, keep fasting because it's good for your health. Hope this might help.
