Ok so i havent gotten my period in about 2 months now... my period has never been normal ever. the first time i ever got it i had it for 2 weeks. and then it has ranged from every 28 days to every 40 days and sometimes even skipped a month. but never has it skipped 2 months. and i normally get it from anywhere from 3 days to about 5 or 6 days.. now i took a pregnancy test about a week after i expected my period, which would of been feb 22nd, and it came up as negative.. and i still havent gotten my period and that was on feb 26th, that i took the test, my last period was on jan 20th.. should i take another preg test or wait it out? but im also wondering.. if your takin a multi vitamin for a couple months then just stop taking it can that mess with you period??
