Havent had a period for 7 week

Hey, im 14, and havent had a period for 7 week. I know im not pregnant as my boyfriend and I are always safe, however I have always been regular and am slighly worried, can anybody tell me if this is normal and what it could be?
Thanks x

first of all, even if you use a condom there is still a slim chance you CAN get pregnant...it doesn't nessicarily half to break either...there could be a tiny hole you cant really see, it could leak out of the top...its always possible, even when it's safe. You shouldn't be having sex unless you are ready to get pregnant...because anyone can get pregnant with or without protection...
although it could be caused due to stress, or excersize, or diet, also periods can just go irregular for a while...or stay irregular...don't worry about it...I'd say just take an at home pregnancy test so you can rule that out. if it says negitive, you may want to consult a doctor to find out why it's so late...it could be many differant things!

im on the pill also, we use both.

it's doesn't matter there is always a chance just do a test

if your just starting your periods gonna be irregular for a while. but if he used a condom everything shuld be fine so if you think something is wrong you might wanna talk to somone you trust or a doctor.

I started when I was 9, im 14 now
