Irregular bleeding due to taking a pill

Q: A sister spotted first day (Thursday night) then immediately took the pill. She did not spot at all for 6 days. She had forgotten to take the pill at lunch time on Wednesday and then she spotted immediately. She then took the pill she had forgotten to take and the spotting stopped. Is the 6 days her haidh days? Can she make ghusal and read Salaah as she is clean now? She leaves for home on Saturday after which she will stop the pill and this will start her proper bleeding. So which days are her haidh days? Does the first six days which are tuhr are they haidh days or after she stops the pills are those haidh days?

Waswasas

Q: Please can you assist me with the following: My family eat non-meat products from non halaal restaurants such as fish, vegetables etc. I am therefore concerned that their clothes become napaak as a result of 1.) crumbs from their food falling onto their clothes (which could potentially be contaminated) or 2.) from sitting at such places as there is always a possibility of crumbs of the non halal food being on the seats. Whenever I see crumbs on their clothes I begin to get concerned however I am not certain if the crumbs are from eating at a non halal place or from eating elsewhere. I would therefore like to know if this makes everywhere they sit subsequent to eating at such places e.g. couch, bed, car etc napaak and would I have to wash it thrice every time this happens? Furthermore since I am not certain regarding the source of the crumbs, do I also need to was their clothes thrice.
