Bleeding after a miscarriage

Q: I am confused whether my bleeding is istidah or posnatal. I had an eptopic pregnancy at 11 weeks. My treatment for eptopic pregnancy involved a D and C and an special injection to terminate the eptopic pregnancy. Since the treatment I have been on heavy bleeding for almost 5 weeks and now on my 6th week I am still getting brown discharge. My doctor said the bleeding lasted so long because of the injection and she also said that though this is not a postnatal bleeding, she recommended me to wait for 6 weeks until I start praying. Now that I am at the end of my sixth week, I am still having the brown discharge after the 5 week long heavy bleeding. Should I start praying or not? Please advise.

Gifts received before nikaah

Q:

1. I have married my husband with the intention of fulfilling my needs and after it to get a divorce from him. But now Alhamdulillah I realized that it’s very wrong and now I love him and want to be with him. So is our marriage valid?

2. Before marriage we did many things but not intercourse. So should I only repent to Allah?

3. Before marriage he gave me gifts like dresses, laptop, etc which I’m still using. So will it be permissible to use it now?

4. Few months ago he once said that you are divorced thrice but few minutes later he said it was due to anger. It’s been 2 years now but we still cannot do intercourse because I fear a lot. So is our marriage valid?

Selling fireworks

Q: Is it permissible to sell firecrackers during Christian holidays and offer freebies to attract customers to come in the store. The money from the firecrackers will be kept separate. Can you sellitems that are not legal to sell and can get fined for if you ger caught? After doing the above, can you still praise Alllah for makeing your business so successful and giving you so much barakah in the rozi and even if you are paying taxes. Please clarify.
