I'm almost 31 weeks pregnant and today I've noticed less movement overall, but it's more spazzy/frantic when it happens. Is this something anyone has experienced? Is it of concern? I've messaged my doctor's office, I see him Tuesday, but I don't know if it merits a call to the nurse line or whatever at my doctor's office.

I haven't googled yet, and I'm a little extra concerned because of issues I had in my 3rd trimester with my son. But because of that I think I'm more worried than I should be.
