Deciding if I need to taken daughter to er

So randomly my 6 month old was able to sleep and I picked her up and she threw up all over and it was a lot and chunky , she was laying on my bed at the time and after that she started to have lots of saliva in her mouth and a lot of mucus in her nose. I think some vomit got in her nose and she sounded congested, no matter how many times i suctioned there was still a lot. So I cleared it all but as all that was happening here breathing looked strange . Like hard of breathing. But what is weird is once I got the rest of the stuff out of her nose . She went. Back to normal and breathing . So I’m kinda worried , I want to take her to the er but at the same time I don’t because as of right now she seems way better. It just worries me because it’s rsv season . But she doesn’t have a coupe or blueish tint to her, only the weird breathin in the chest and vomit that fixed itself .what do you guys think it could be I took some screenshots of her chest from the video I took and it’s her chest going I’m but like I said now it’s not doing that now.
