Pregnant with Ex BF and now have new BF

Looking for advice or someone who has a simular situation.. I broke up with my boyfriend a month ago. I met someone new just a few days later and he's my perfect match! Never felt this way with any other guy before. Anyways, after being with this new guy for 2 weeks I found out I was pregnant. I KNOW its with my ex. My new boyfriend is perfectly okay with it because we are so in love already its unreal. But my ex still has feelings for me and now we're having a baby. I WILL NOT get back with him just because we're having a baby. But anyone else in this situation? How do you deal with your ex always being there when you're trying to be happy with your new life and baby. Do you have him at the appointments or let your new boyfriend be there because he's your support through your pregnancy?
