Should I follow up? Interview

Interviewed with large public tech Ecommerce company. Made it past the HR screener. A week later she follows up through the jobvite program and asks for times I can interview this week with the team. I got the email 5 hours after she sent it through jobvite bc that software sucks.

I emailed her back with times this week and its been two days and haven't heard anything back, only two days left in the week.

Should I follow up?

I have already followed up with her between the interview with her and her last email to me (the one trying to schedule the interview with the team). I'm wondering if the jobvite messages are getting lost in route?
