Does it really have to happen?

Ana • My husband and I are expect our first child. We are beyond excited!
This might be obvious to some people but I honestly don't know the answer to this. Does your belly really have to drop before the baby comes? Are there any of you mommies out there who didn't experience this? I'm 37w2d and I look the same lol (no belly dropping here), but I was just curious if it's a step in the direction of "baby is coming!" Any feedback would be appreciated. Thank you!
