Pregnant didn't know it . It could be your body wanting to have it's period but it can't because you pregnant or miscarrying
I dont think you can but you can have spotting which may confuse you for your menstral. Spotting is much lighter then ur actually period.
This can be a indication of pregnancy. If your already pregnant, then mention the bleeding to your doctor.

It depends on what your doing with it. If your towing, heavier. If your on the beach, lighter.
