Some people take time to connect with their bump, we are all different! I find this site helps, because I was having a difficult time trying to connect, because I'm only 17 and I'm very nervous about becoming a teen mum, but chatting to the lovely ladies on this site really helps you feel like you have loads of people behind you, and talking to other pregnant women and mums, really helps you to get excited about the little one inside you!
It's common to feel like you aren't going to be a good mum, but I'm sure you will be a great mum! No one gives birth and is immediately perfect mum, it all takes time, practice and experience, and I'm sure you're going to love every minute of it!
Good luck with the rest of your pregnancy, and I hope you start to feel a bond with your baby soon! xxx
