Well My best friend Tina was pregnant and she was the same age as you. She is 16 now with a beautiful baby boy named Anthony. She didn't tell her mom until she was at least 3-4 months. because thats when she started showing. Well she went to clinics. Im pretty sure they are free or don't cost that much, but tell your mom when you feel comfortable. Tina told her mom while I was there, she started crying and said that she made a stupid desicion that changed her life. Her mom cried for awhile, they didn't tell her dad for awhile because he gets angry really fast. Her mom talked to her father about it, he didn't talk to her for awhile, and Her boyfriend Taylor wasn't allowed to see her for a very long time. Only short visits when her dad wasn't there. but now everything is really good.
