I use withdrawal , my period has always been regular . The past few months has been super irregular. Missed my period completely in October, took a test it was negative . I got it in November & I got it two weeks ago .

However , I’ve been super exhausted , fatigued , I have been bloated , more gassy than normal , headaches & I had the worst back pains yesterday . Also my breast have been super sensitive and very itchy the last few days. any ideas ?
