My Mum, her sisters and their mother had to use folded clothes as sanitary protection, which had to be soaked in a bucket under the sink, washed, dried and re-used.
I am eternally grateful I never had to do the same. I flooded frequently despite maxi plus san pro, have soaked car seats, had people think I was miscarrying and generally suffered excessive blood loss most months. I could have an 18-day period no probs, and there's not a gusset that could cope with that [grin}
I say thank goodness for people who historically battled for san pro for women and girls, and wish more was being done for them in Third World countries where none is available.
Obviously there is nothing to be ashamed of, but it's an inconvenience I wouldn't wish on anyone.
