Friendship and pregnancy?

So me and this guy dated for a few months. We broke up and now we are talking again. We’ve had a very up and down relationship during the breakup because he really cared about me and I kinda left because I wasn’t ready. We haven’t had a talk about what we are as of now however we talk in the phone constantly and we’ve been having sex. He’s made comments about how he does want kids but under the right circumstances. He also jokes about how he knows if I end up pregnant I won’t tell him. He knows I’m not on birth control right now and when w have sex it’s unprotected. If I do by chance get pregnant should I feel bad?
