Does anyone feel like they're not really pregnant?

i know that sounds weird, but im 20 weeks along with our second. our first was only 8 months old when i got pregnant again and this pregnancy is so different than the last. what i mean is, its like i dont even notice im pregnant because its almost.... normal. its strange because i dont have the anticipation like i did with our first and it seems like its all ping in a blur. of course, im excited and love feeling this baby moving and we got to see him or her on an ultrasound last week. im just worried that since im not as "connected" during this pregnancy that i'll feel the same thing after the baby is born. i know that it'll change the moment i meet him or her but to be honest, im so stressed out about money/work/life in general like most and we're working so hard to make things better that its better that this baby comes later rather than sooner (it was a rough winter) and im not as anxious as i was with our first.... is there something wrong with me?
