well im 16 and think i might be pregnant but the thing is i was on my period for 2 months and havent had a period for almost3 months....my periods were irregular at one time but i got on birth control to regulate them..they have been regular since i was 12 but when me and my boyfriend had sex i wasnt on my pills for a week...i took a pregnancy test and it came out negative..i have symtoms like nausea and growing and tender breasts and i have mood swings alot...someone please help what could be going on?

first you have to check with your doctor if you dont have one make an oppointment with plan parenthood if you really want to keep it confidential without your parents knowing whats going on with you. they check for everything that might be possible that is causing these things with your body. next i have to tell you dont stop taking your birth control even if you are sexually active with your partner because from experience you period will become very hard to track
