Keep your head up, stay positive. Look to an older family friend or sibling if you can. No one can make you have an abortion. They've passed certain laws that refrain you from having an abortion after a certain period. If I can give you one piece of advice, don't give up on school, it will benefit you in the long run. Don't focus on your child's fatger. He will ultimately make his own decisions. You can't force him into being a dad. You guys are so young. Just think about you and this baby. Do everything you can to make sure he/she has the best life possible. Good luck.
Hang in there! Google for crisis pregnancy centers in your area. They would love to help, and can connect you with all kinds of support for your pregnancy and for making plans for afterwards.
