I don't know if I really want this or not...(trigger)

We tried almost a year ago. It didn't happen. Then we broke up, got back together, had sex and it happened... I didn't have time to think if I really wanted to even be in this relationship, let alone have a life time commitment of a baby. He doesn't know if he wants the baby either. I don't know what to do. I found out pretty early. I found out at 3 weeks 6 days... So, I have time to think. I even called the clinic to ask about the procedures just in case. I have children. Even though I was shocked when I found out I was pregnant, it had sunk in at this point, I think. This just doesn't feel right and I'm so torn 😢
