Wearing tampon may block the flow sometime. That too if you have irregular periods better go with a normal one. In case of emergency requriements you can use tampons
Well if you don't change your tampon/pad then yeahh. It's unhygienic to not clean yourself.. Dur. Of course it would smell bad.
No.
Irregular choppy wear in a tire, bad wheel bearing.
No, it's not bad to use a tampon in the pool for the first time - if you choose to use tampons then there'd have to be a first time. You may want to consider menstrual cups instead of tampons as they're safer so you can wear them for longer and with light flow, plus they don't leak like tampons. If you do use tampons just make sure to use correct absorbency for your flow and change before the pool.
No, it isn't a bad word. It is a product. It is like asking if paper towels are bad words.
It's neither good nor bad to wear shorts during your period, as long as you use sufficient menstrual products to prevent leaking you can wear whatever you want.
My periods are a little irregular. They start at random times for no reason at all, but I am completely healthy. Don't worry about it unless your periods start to get irregular all of a sudden. If your period cycles have always been a bit irregular, don't sweat it.
Many women experience irregular periods. Speak to your doctor about it, they can find the cause of your irregular cycle and possibly correct it.
Nothing bad can happen from starting your period 1 week early. If this happens it is probably because you're irregular but it does not cause problems.
Tampons should only be worn during menstruation, and they shouldn't be worn overnight.Tampons need to be changed every 4-6 hours which can't be done while you're sleeping, the longer you leave tampons the greater the risk of vaginal infections and TSS so regular changing is important. You also need to alternate with pads to allow your vagina a chance to clean itself, and overnight is the most convenient time for you to switch to pads.
If your tampon isn't in properly, it could leak or you could experience discomfort. Those are the worst possible outcomes.
YES! you should totally see a Doctor RIGHT AWAY. Even if your young and irregular, 12 months is far to bad. You might have something wrong inside your body!
