pregnant and caring for a 11month old

I'm currently pregnant (about 9wks). I have a 11month old and lately he's been soooo attached to me. He used to be on a strict bedtime schedule @8pm since he was about 4months & my 10yr old by 8:30. Things were great! for the past few weeks he doesn't want to go to bed unless I'm going to bed anddd he doesn't want to sleep in his crib. His crib is still in my room by the way so he's definitely not alone. We r going backwards. Anyone else going through this? Maybe he's glued to me because I'm pregnant?
