What to recite during pregnancy

By the grace of Allah Almighty I have been blessed to be a mother (second time). My first child had congenital abnormalities including heart and intestine issues. He passed away after six months. Can you please guide me to do what during this duration in order to stay safe ? I recite Quran regularly (Alhamdulillah), recite manzil and some good books also. Due to my condition I have been advised to have bed rest. Lying whole day all alone makes me frustrated and depressed. I feel so lazy I don't want to do anything and at times I feel so low. Kindly guide me some zikr that I should make.
