Have you changed any birthcontrol methods? This could also depend on your age and what your body is going through. Have you talked to your doctor/OBGYN? Do you experience any cramping or pain with this?
I have an irregularmenstrual cycle without Myomin. If I take Myomin my periods are regular but as soon as I stop taking it, Im out of whack.
Should I be worried...
that are so regular, they can set a clock to it. Others are so irregular that they've given up looking for any trend... in over a year and then start up again.
Could the bleeding be due to wearing a very tight skirt? Unlikely...
