You should find a place to pray that is secluded, and mustn’t pray in public unless as a necessity. In this case, you can keep your face covered and you can pray on any ground whether clean or dirty as long as there is no najasah or impurity that prevents prayer.

 Actually I am a medical student and we have to give our test in wards so we have to sit with the patients. We don’t get any break. My question is can we pray in naqab if there are non mahram around us? And if we have bench available only and the floor isn’t clean, then can we sit and pray on the bench?!

When I was younger, I used to sometimes have an issue where I would think that my menses might have started as I would have some discolored discharge and cramps. So I would stop praying, but then it would take a little while longer for my menses to actually begin. Would I have to make up those prayers that I missed or would they be excused since I thought I was already on my menses?
