Is it okay to have a body massage even though I have my monthly period?

A lot of old people say bawal daw. I always hear this kasi lagi ako ngpapamassage. Pro since I do it on a weekly basis, kahit may period ako tuloy lang. I know I might be risking something kung totoo man nga na bawal, pero kasi if I really need a massage, regardless if I have a period or not go ako. Hindi ko kasi kaya back pain ko every time so pag need ko na ng massage, I go to the spa. I've been doing it since 2003 and so far wala naman bad side effects
