20 weeks and movement isn't consistent

Missy

Hey ladies, just seeing if any of you can relate, or better yet ease my mind! I am now 20 weeks and some days I feel my baby girl all day long with her little movements... And then other days I may not feel her at all (like today). It worries me... Is this normal? When should I feel her consistently? Thank you!
