Does asking someone to look at their message request seem desperate?

so i work with this girl and she’s somewhat quiet which i understand since it’s a loud environment and her English is ehh. but on instagram she has her messages set so not everyone can message her and if someone new does they have to get accepted. i texted her once 3 weeks ago but she still hasn’t seen it. do i tell her or what should i do? like i really like her and i think i’m getting signs she likes me too. and i’m the only guy from the job that she follows which could also be a sign
