Pregnancy seems unreal?

I feel so badly, this is my second baby and I feel unconnected. I’m already 15 weeks along. I’ve seen him in the ultrasound. I know his gender 💙 but I constantly forget I’m pregnant. With my daughter the pregnancy consumed me from day 1 I was obsessed and in love, talking to my belly, taking care of myself (taking walks, rubbing oil on my belly, etc.) the most I do with this one is try to eat healthy and sometimes take prenatals. I feel like I’m not going to have a strong connection with this baby and it scares me. I wanted a little boy so bad, and I’m having one but I can’t seem to feel any different. Have any of you moms experienced this? I feel so bad :(
