Hi, and I'm sorry you're feeling lost and confused. There is power in educating yourself about your cycle and your body as a young woman. For now, I can advise that there are pregnancy tests that you can purchase at a drug store that will pick up the hormone level in your urine very early. You can get a pack and try now, and if the test is neg. then wait a few days and take the test again. (4-5 days later) Your body will begin to produce the hormone levels at a stronger ratio as you progress into your pregnancy. If it's positive I would then advise seeking a friend who has your best interest at heart and who has some faith in God. Your mom may be a wonderful person to turn to at that moment and discuss her supporting you in this and if you feel you cannot keep the baby, then look into adoption opportunities. But, please don't resort to murdering your baby. You will never be rid of the pain and loss of that life.
God bless you in your situation,
