Not connecting with baby..?

Hi! I'm a ftm. 27weeks + 5 days. Due August 18th!! I'm just wondering if there are another first time mommies who don't feel connected to their baby yet? Like I love my baby & love to feel her move but it's like I don't have that connection yet. I feel as if I won't be good enough for her once she arrives & really don't want to fall into ppd.. 😕 I see other pregnant ladies who talk to their baby bumps & have a bond already but when I try I just feel stupid. Like if this isn't for me? Any advice for me to get over this? Anything helps! Thanks in advance.
