All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
It is not necessary for whoever breaks the fast to remember or intend to make up for a particular day –the 4th or the 5th or else –of Ramadan; rather, he should make up the days with the intention that they are from Ramadan because we are not aware of any religious evidence of this condition, and no scholar has ever mentioned this condition.
However, if you broke the fast without any sound reason, then you are obliged to repent. If you also had intercourse with your wife during the day of Ramadan, it is an obligation to expiate for it as well [in addition to making up the fast] as explained in Fatwa 84189.
