Irregular haidh

Q: I’ve been having irregular periods ever since the first time I got it, 3 years ago. I get the brown spottings/discharge which I am told is considered as my period. Recently I got my period regularly for two months in a row. Till last month which I did not get it at all. I then got the spottings at the end of October and beginning of November and considered that my period. After those 10 days were over, I got my actual blood period 8 days later last Saturday.

My question is which one is considered my period? And do I not pray my salah for this period and make Qadha for all the missed ones last time or consider this as haiz and pray my Salah’s while I’m on my blood period right now? 

Women working

Q: I am an engineer. My salary is an amount that I can just afford to take care of my family. I will not really be saving anything. However, my wife is a dentist, she did not start her practice yet. She just passed her exam a month ago. I permit her to see female patients by opening a surgery. But she wants to be a BCS cadre. This is the highest prestigious govt. job in our country for practicing in a govt. hospital. That means, she is not only interested in the money but also social dignity. If she becomes a dentist in a govt. hospital, she will have to face males nurses and male patients also. If she can avoid male patients, she will still need to talk to other male doctors as well as her colleagues. She will also need to talk about some unnecessary aspects e.g. can she say to her colleague, hello Mr. X, how are you and your family? This is not directly related to her profession but she has to do this. Please note that she wears the purdah but she is very keen to do that job. I am not interested in her doing the job due to the reason I mentioned above, but she forces me again and again. If it is permissible then I will permit her and save my mental peace.

Feeling depressed after extracting a tooth

Q: I know my question is very strange but I am 21 year old female.. I had the option of either doing a root canal or pull my tooth out. I decided on pulling it out. And since I pulled it out I've been crying out of regret cause I can't just replace it due to other complications. I am sad because it's gone. Can I say this was Allah's plan or was it the consequence of my own choice?
