Idk what to do

I had a pattern going for my baby im about 28 weeks. The last few days I've barley felt her or her pattern anymore. I found her heart rate on my doppler and. Even laying her about 35 min bow and have maybe 5 movements in not very strong kicks. My doctor said he isnt going to tell me. Ot to go to the hospital for the stress test but if I dont trust my doppler enough to go in. Am I over worrying? Should I go in? He said notall kicks are hard but I've noticed her being much more active then lately. I'm afraid to go waste hundreds and everything be ok idk..
