Primary fermentation question

Hello all,
I have a quick question. I started a batch of wine Friday night from a kit. Now ( Mon nite) it doesn’t seem to be doing much. It was going gang-busters Sat and Sun. There is pressure( the bubble in the airlock shows a positive pressure in the carboy). Is this ok? I also notice the smell is different. I’m planning to transfer to the 2nd fermenter this coming Thur nite , provided SG is 1.010 or less, per instructions.
Any advice and insight is appreciated.
Thanks again,
Charlie
