Can you take progyluton before your periods start?

It depends on the reason for taking progyluton. Progyluton is a combination of estrogen and progesterone, and it is the brand name for norethisterone and ethinylestradiol. It is usually used for hormonal contraception, to regulate menstruation, or to treat certain hormone-related conditions such as endometriosis or polycystic ovary syndrome. In general, progyluton should be started on the first day of menstruation, or within five days of the start of menstruation, unless you are taking it for a specific condition such as endometriosis or polycystic ovary syndrome, in which case your doctor will advise you on how and when to take it.
