A blood test is usually done early in pregnancy to make sure you are pregnant so don't worry about hime wanting one. And if he didn't finish, that doesnt make a difference. Small amounts of sprem are released the entire time you are having sex. And although it is difficult to get pregnant from just that, it is possible. That's why withdrawl is not a recommended form of birth control. He may just be really scared at this moment. That is a lot of responsibity thrown at him all at once. If he wants a paternity test, go for it. Don't be angry that he wants one. I know that it hurts to think that he doesn't trust you, but if it will prove to him that he is the father and make him step up and help, then it is worth it. I got pregnant for the first time when i was 17. And even though my now husband knew it was his, his family pushed for a paternity test. But once our daughter wazs born they knew she was his and backed off. I hope that gives you some comfort. Sometimes it takes seeing the baby, whether through ultrasound, or after birth, for a father to step up and be involved. And do tell your parents, if you are in a safe situation to do so. Whichever one you are more comfortable with, go to them and let them know, then ask for help with the other. It's better to tell them know than later. I know its hard, but being a teenage mom can be done, and with a little support its even easier. Take care and let me know how it goes.
