I second that. Just call doc and explain. They will have better idea :)
I would go to L&D if you haven't already.
This happened to me maybe a month or so ago. The nurse at my doctor’s office who answered said it was fine and even just flutters the baby is ok. I told her I did not feel comfortable with that, I know my baby’s movements, and would like to be checked. I was sent to labor and delivery (our ER doesn’t handle pregnancy related issues), took them forever to find her heartbeat but she was completely fine. She was just being stubborn. She hated the fetal monitor and started moving nonstop to get it off. Labor and delivery told me any concerns no matter what it is, better to be safe. I hope everything goes well with you and baby!
Try some orange juice and see if she gets more active
I would call your doctor today, explain everything, and let them tell you what they think. Just to be safe
