Haiz, Istihaazah & Nifaas

Bleeding After Nifaas

Q: A woman had 40 days of nifaas. Then there was no bleeding for two days. Thereafter she started to bleed. What would this new bleeding be? Would it be istihadha or haiz? Also, if it was haiz, would it be counted according to the old habit the one before she got pregnant?

Bleeding in Pregnancy

Q: I am pregnant Alhamdullilah and last week I had some bleeding. Alhamdullilah the bleeding stopped but now I am unsure if I can begin reading my Salaah as there are still some black flaky discharge. My underwear remains clean and I can only see the discharge when I go to the toilet. Can I make ghusal and start reading my Salaah or should I wait until the discharge is gone completely.
And please can you suggest a dua that I can read to keep my unborn baby safe and that my baby grows healthy, normal, strong and pious.

Seeing a Yellow Streak on Alternate Days of Haidh

Q: My haidh period starts from the 19th to 25th and the rest of the month passes in Isitihaza, but for the past few months its happening that during my haidh period there is almost no bleeding or very less, but my isithaza passes in full bleeding. Even this month it starts on the 22nd with only a yellow streak on alternate days, counting these days as my periods I am not performing Namaz. Is there a possibility that my habit might have changed? It has been a month and I am taking treatment as well. Hazrat should I stick to my current habit that is 19th to 25th even if there is no proper bleeding or has my habit changed?
