I'm 24 weeks and 4 days. my baby has been moving around a lot this past hour or so and they're very hard jerky kicks. should i be concerned?

Please call your OB specialist. If there is cramping pain, spotting or fever, please see the Emergency Department. Fetal movements though are usually normal. The evaluation of the baby should be performed to ensure normal activity and heart tracing. An ultrasound may be indicated.

Probably not. As baby gets bigger, movements will be stronger. Increased movements over periods of time will not be unusual. As long as you are not having cramping, bleeding or leaking, most likely nothing to worry about. If concerns persist or if you are worried, reach out to your doctor.
