Why would I be late for my period?

Okay, I know I'm not pregnant. So that is totally out of the subject unless you can get pregnant from giving your boyfriend head. But I know you can't.

I'm usually on time. I've been late maybe 3 times. But usually I'm a couple days early. I'm now a week late. I got the signs of getting my period. My back always hurts when it gets close to my period. Well it hurt for a few days, but nothing happened. And now the back pain will happen one day and be gone for a few and be back.

I am stressed out. But I've been stressed out the past 8 months and I've still gotten my regular periods. I just took on a second job yesterday. But that shouldn't of made a difference, since I just started it yesterday. But my other job ALWAYS stresses me out because I'm a supervisor and none of my night shift wants to work. But like I said, I've been stressed out for the past 8 months. My mom passed away, I moved out on my own, I have money problems. But I still got them.

What could be wrong? I'm 19.

Too much stress (which you obiously have) can delay your period, even make it stop all together. If it continues for any more than 2-3 months i would go see a doctor just to make sure everything is alright.

Just try to find a way to manage your stress because too much stress can cause another thing: Crohn's Disease, it is an intestenal disease that my mom suffers from, and it is uncureable. I am very sorry about your mom, i hope i helped a little bit.

Have some healthy food. At this age late periods are common. They will stabilize when you advance in age. Irregular food habits, strain and improper sleep habits delays the periods. Nothing to worry. But you should be careful with your boy friend, if you have( do not think otherwise)
its too much stress. it's happened to me. my boyfriend of 3years broke up with me and my period was a week late. the best thing to do is to physically get active because it gives you natural endorphin's and makes you a happier person. get out alot so you can have fresh air.

the only other thing that i can think of is if you have an eating disorder of any kind. my friend would miss her periods because she had no body fat. she didn't have her period for like 3 years! we found out later she had an eating disorder (which i could visually see) and told her she needed professional help. they told us she didn't have her period because she had no body fat.

hope that helps
You have way too much stress in your life and you need to deal with it soon. You mentioned having lost 75 pounds in 5 months, that alone could be the reason for your periods stopping. You need to find some outside help in the form of a clinic that bases their services on your income. Call your local health department and start your search for help there.
Chill. I am freaking out about my period as well and I've had unprotected sex last month. I don't have a dad and live w/ my step bro who treats me like $hit ....there are other people in ur shoes out there. Love
