Follow up after a job interview

Hi nannies! I had a phone interview with a potential family two weeks ago and it went great. Last Friday i met them in person and we had got along so well, I think we would be a great match and I think they felt the same way. On Monday, MB sent me a background check and it passed, but she hasn’t said anything yet. Is it too soon to message her and check in? I don’t wanna seem desperate, and I definitely don’t want to annoy her but I really want this job. Any advice is appreciated!
