So i got my period when I was 13 and I’m 18 now but my periods are still unpredictable and ive gone a year and a half without one before... ive just recently started being sexually active and I don’t know if I should be extra precautious or just continue doing what I’m doing... I’m currently 124 days late and only have had sex three times but still... idk what to do... my mom says I shouldn’t worry about irregular periods but you would think... after 5 years they would regulate.. she also doesnt know I’m active... advice is greatly appreciated
