Hi dr, after almost 6months after premature delivery i feel weaker than i used to before pregnancy. is it normal?

No: You may be tired from doing your usual chores and looking after a baby. It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated.
