Other kids and pregnancy

Has anyone gotten pregnant and their child got reallllllyyyy clingy? I know this is heard of with animals. Anyway I think I'm pregnant but I'm not due for af until Monday so I'm not positive and my gosh my daughter will not leave me alone! She's 2.5 btw. If I shower she cries, if I close a door without her in the room she cries. It's fine but frustrating. So I was just curious if that happened with anyone!
