Slow Responses Recruiter

About a week ago a recruiter reached out to me via email about a position that I recently applied to/was excited about. I responded back within a day and they responded early the next morning. I replied later that same day and they didn't email back for another two days, so I sent a follow up email which they replied to. They haven't replied since and it's been about 5 days, should I send another follow up email? So far the times we have picked to schedule a call haven't been lining up which is why it's so back and forth, but they're making it harder by taking so long to respond. Would it be too pushy to send another follow up email / what should I do as I was really hoping to get this position
