Why do my stomach and back hurt?

My stomach and lower back have been hurting for 2 days already. I dont know wy. Im NOT on birth control and when I have sex, my boyfriend doesnt ejaculate(sorry for spelling) in me. Today my back pain has increased and now my sides are starting to hurt..I had a head ache yesturday for about 10 min. and also when I went pee about 45 min ago..my stomach hurt a lil more. I had my period last week and it only lasted for 3 days and it was super heavy..usually my periods last 4-5 days and they are light. Can anyone help? Like has this happened to anyone else? Is it normal?

I dont think it is normal to be in pain. There could be a number of reasons your lower back is hurting, but if you are asking if you are pregnant.. then you need to go take a birth control test. Even though he did not ejaculate inside of you, there is always still a chance that you could be pregnant. It is better to find out now, than wonder if you are or not.

To my collegue above, taking a birth control test will NOT find out if she is pregnant. Birth control is used to prevent pregnancies.

As for linz> it is most likely you are not pregnant, but if you are sexually active, you really do need to be on birth control, and your boyfriend needs to use a condom. Less chance of getting pregnant, and getting an STD. If the pain doesnt go away soon, I think you should call your physician.

Dear linz001,
First of all just because your boyfriend does not ejaculate in you doesn't mean you can't get pregnant. Men have what is know as pre-c*m. This is a fluid that leaks out of the pen*s prior to ejaculation. This liquid is full of sperm. The method you are using is called withdrawal method and is never, ever recommended as a birth control method. Also if your boyfriend ejaculates and you or he has any on your hands, under your nails, or on bedding and you are touched on or near your vagina; sperm stays a live for a period of time and they can travel. So it will only be time till you are pregnant. Are you pregnant now even after your period...lets hope not but there is a great possibility since you do not use a condom or birth control. At your age periods will change and that is normal...but you now need to be tested for STDs ( some STDs can make your back and stomah sore) and get a pregnancy test to make sure.
Sue...good luck

well there is a possibility you are pregnent but when your pregnent you dont have your period and you should go to a doctor for your back you might have pulled something like cleaning.picking up something or from a certain position when you have sex and get a pregnancy test to see if you are pregnant
