I wanted to ask, if someone has got an implanon implant (birth control) and is spotting on odd days, is one allowed to fast on such days? This implies for qadha fasts, sunnah fasts and also wajib fasts May 24, 2021 by Hasan mahdi If it is just spotting which comes on and off then yes one can fast however the rules of istihadha would apply for namaz.
