He doesn't want kids and we agreed not to, but I'm feeling kinda queasy? What if?

Take a pregnancy test and find out if you are pregnant or not. Why worry for nothing. Then my advice would be to tell him if you are pregnant . He deserves to know since he is the father. If you are sure that you are on bc and that you were faithful in taking it on time then I don't think that you have anything to worry about. Maybe he would make a wonderful father and if you are pregnant it was an accident maybe he won't be so mad at you . I would not terminate the pregnancy but that is just me. Talk to him about it first and follow your conscience about what is right for you. Instead of terminating the pregnancy have you ever given thought of having it and giving it up for adoption instead. There are so many people out there wanting to have children and can't . I am not suggesting that you do that I am just giving you another option to think about. Good luck to you.
