Women's Issues

Q: When my period ends and the time for salah is still there, I understand that the specific salah of that time is obligatory to read. I have more of an inclination to believe that this is what I did in the past months where my period ended - before I had learnt of this fact and I’d like to think that even if my period had ended and I didn't have enough time to do ghusl and read salah in the time, I still did qadha but because I’m not 100% sure, do I have to make qada of all the previous months on the day in which my period ended to be sure or can I leave it?

Q: In the past I never really paid attention to making up prayers that I missed due to the adhan beginning before I was able to read that prayer.

I forgot the ruling (e.g. if menses stops at isha then pray maghrib and isha and if menses begins at zuhr and one hasn't prayed it, then they have to make it up later).

I’m going to make up the prayer I missed for the recent menstruation cycle I had. Am I allowed to forget about the ones I might have missed in the previous months? It would require me to have to look at past prayer times from different timetables and make estimates and I may have to make up a lot of prayers.

Q: I normally get my haidh on a Thursday which is tomorrow but this month I saw some spotting on Tuesday which was yesterday and today there isn't anyting. Considering I expect my haidh to start tomorrow, do I read salaat or not? 

Q: It is not permissible to shave underarms during periods, what is the ruling for shaving moustache or other facial hairs ?
