Q: How does a pregnant lady make Salah?
A: If she cannot manage to perform Salah standing then she should sit on the floor to perform Salah. She should make Sajdah as normal on the ground if this is possible.
If she cannot manage this then she may sit on a chair and perform Salah. She would then make Ruku and Sajdah by lowering the head (indication). The indication for Sajdah should be lower than that of Ruku.
And Allah Knows Best
