I'm 16 and may be pregnant, help!?

i'm 16 years old and i'm not sure but i might be pregnant. I did have unprotected sex about a month ago, not exactly sure the exact date but i remember it was a little after my last period. my periods aren't always regular, but i was supposed to get it around the 16th which means i'm 6 days late. i've been cramping for about 3 days, and i'm having a little bit of a white discharge. i dont get much sleep, i eat pretty normal, and i dont think im stressed. but, i am getting a strong smell from my vagina so i'm not sure if i may have an infection. can that be a reason for a late period? please help!I'm 16 and may be pregnant, help!?
THIS WILL TEACH YOU TO NEVER HAVE UNPROTECTED SEX...SCARY HUH...WELL YOU DESERVE IT..YOU DO KNOW WHERE BABIES AND DISEASES COME FROM DONT YOU...YOUR TOO YOUNG
If you are able to, I would go to see my doctor. If not your doctor then look on line or at your white pages to find your local planned pregnancy place (they have free testing and counseling services). Some planned pregnancy places are very pro life so be prepared, talk to any close friends you have, it is your decision either way. Also, it may just be a yeast infection. Go to a pharmacist at a drug store and tell them your symptoms, they will recommend a treatment for you (like monistat or something. Other then that good luck, I am sure whatever happens you'll be OK.
You do not get a "strong smell" from your vagina due to a late period. Sounds like you could have an infection going on. Call your OB/GYN to make an appointment so you can get a pregnancy test and get tested for STDs and infection.
