I work as a midwife in a government hospital. Sometimes I have immense pressure at work with consecutive births, and I cannot leave my position because I am the only one in this department. I miss my prayers. Is it permissible for me to combine two prayers due to the necessity I am in, due to the lack of time and the clothes that are stained with blood and the difficulty of changing into other clothes? I feel very distressed when I miss my prayers.
