Less movement at 23 weeks

I am pregnant with my first baby and am currently 23w+5d. I started feeling movement about 2-3 weeks ago and for the past few days have felt very little movement. I've been using a Doppler and have been able to hear a strong heartbeat. I've also tried drinking cold water, Orange Juice and other cold drinks. I feel movement just very rarely throughout the day. I feel like I'm worried about something new each week!
