Cannot fast ramadan-medical exemption...?

Ramadan Mubarak sister. I understand how you feel, last year i was pregnant and did not fast and felt that i was not really involved in this blessed month. Try giving up something else instead as well as say feeding a poor person for every day you don't fast. It is important to break fast with everyone else though and to eat some dates before 4th pray. Your intentions are good sister and may Allah bless you for that. Insha Allah you have a wonderful Ramadan for you and your family.
