Should I be worried

I am 17 weeks 6 days and I felt movement a few days in a row and now I haven’t felt anything the past few days, and I’m freaking myself out! This isn’t my first pregnancy I have a 11 year old and 9 year old.. but I had a early miscarriage at the beginning of August and got pregnant again the end of August and since the miscarriage I worry about everything and get myself worked up.. should I be worried that I haven’t felt anything the past few days? I’ve tried cold drinks and changing positions and still nothing!
