Take easy digestive food . Consume more fluid . Take khichdi with pure ghee. It will help in smooth bowel movement.

Please follow normal non spicy home made food diet. I am also constipated but i am taking a normal diet.

No no. Nothing you eat will affect the baby. In fact, avoiding spicy food and gassy stuff is advised Coz it burns you and might affect the stool of babies. However chapati won't.

It won't cause baby for loose motion??

Yes yes sure you can. Having chapati won't affect your feed.; Just have healthy things that are home made and drink lots of water and fluids.
