First, let's differentiate between a stall (what you're going through right now), and a plateau.
A stall is just a temporary fluctuation in overall weight and is not indicative of an issue. Stalls are perfectly normal and to be expected. After all, your bodyweight is made up of lots of other stuff besides fat, so fluctuations are to be expected.
More than likely, you actually have continued to lose fat the entire time, it's just being masked by a concomitant rise in some other component of your overall body weight. The most likely candidates would be fluid retention, or stool weight. Most of the time for a stall, I wouldn't recommend any adjustments since it's unlikely that there is really any issue with fat loss.
A plateau is like a stall, but longer. I typically wouldn't consider it a plateau until you've hit more like 6 to 8 weeks without any loss. In that instance, it would be hard to argue the fat loss was being masked by something else. There are things we can do to work through a plateau, but IMO it's too soon for you to worry about that yet.
