Haiz, Istihaazah & Nifaas

Calculating haidh while doing IVF treatment

Q: In regards to my menses, I have a 28 day cycle... give or take. If I wipe and find a little change of colour on the toilet paper, I know I'll get my menses a couple of days later. Unfortunately, at the moment I've been having IVF treatments and I just stopped taking hormone replacement tablets and on to taking my injections, however, the nurse told me that my hormone medication and injections will overlap for 3 days and then I'll get my menses.

Now, this is the part I get confused because, the day she said that, which was a Wednesday, I had a few days before I thought I'd get my period, but on that day she said that, I saw a slight colour change on the toilet paper, anyway I still kept on praying because the day she said I get them was not the day I saw it, as I had a couple of more days before and I'm glad I did continue praying, because every other time I wiped it was clear and this happened to me for a couple of days, but yesterday, there were spots of blood on my underwear so, I washed and still prayed Dhur, but I again saw spots on my fresh underwear after changing them and now it was closer to the time when she said I was suppose to get them so, I didn't pray my maghrib, Isha or today's Fajr and now it's clear again and I've missed 3 salats and I'm upset!

What do I do in this situation and how can I make up these salats?

P.S. I feel if I do pray at the moment, I feel like I'm doing the wrong thing and if I don't pray at the moment, I feel like I'm still doing the wrong thing. 

Women in haidh entering Aqsa courtyard

Q: Can a woman in menstruation (haidh) enter the Masjid al-Aqsa compound? This is a compound surrounded by walls which contains several buildings such as the Dome of the Rock, Masjid al-Qibli, etc. Is the entire compound counted as the masjid (meaning that woman in menstruation can't enter) or is just the buildings counted as masjid and the rest as courtyard (which a woman in menstruation can enter)?

Brown discharge before the days haidh

Q:

1. I get my menstrual cycle on the 25th or 26th of every month... but before my menstrual cycle begins... when I'm not bleeding yet... on the 22nd or 23rd, I secrete a brown discharge. Can I read my salaah?

2. If during Zuhr Salaah I get this brown discharge, should I only omit my Zuhr Salaah and continue reading Asr or should I leave out the remaining salaahs for the rest of the day?

Calculating days of haidh

Q: According to discretion, when my haiz started it was on 19 march 2010 for 9 days, but I dont know the number of tuhr days exactly. According to descretion 19 or 20 days.

1. How many days should I take as tuhr?

2. I get bleeding for 3-4 days every month now and keep on getting green discharge after every 3 or 4 days, throughout the month. Which days should I count as haidh?
