Yes, it's perfectly normal. Hang in there; this is a journey that can only be measured by the week or month, not by days. Your weight can fluctuate day to day, even week to week, based on muscle tone, what you're eating, possible water retention... fat loss can be masked by these things on the scale.

Just as a side note, we generally tend to define a stall as no weight *or inch* loss for 6-8 weeks.
