Spotting at 7.2 weeks

ND • Ttc
We had planned our vacation to meet family and flew last Friday. Today I noticed light spotting and it is freaking me out. I am 7 weeks 2 days today.  I don't have any abdominal pains and spotting is stopped too.  Should I be worried? I have tried my best to remain relaxed and just stayed in our hotel the entire time we are here. Should I rush to an emergency just to be sure? This is our first baby. I was so careful about flying and talked to our doctor since ours was a low risk pregnancy and made sure I was comfortable and well rested. Was it a mistake coming on this trip? What should I do, I am really worried.
