Hi nether,
A big Aussie welcome to Susan's family. It's good of you to drop in and say "Hi". Hope you like it here, and you stay for a while.
There is a mountain of information, resources and friendship waiting for you here, you just need to jump in start talking and ask any question you like. You're quite safe here and we are very accepting.
What you've explained is very common, particularly for you. It's not uncommon for women in large groups like factory workers to have their periods all very close to one another.
Looking forward to hearing more of your story in time to come, but in the meantime, be safe, well and happy.
Lotsa huggs
Catherine
