I've been keeping track of my weight loss and knew it would slow down once I started getting off the liquid phase and started introducing food back into my diet, but I've gained a pound now. I'm not eating unhealthy, aside from some frozen yogurt yesterday. Is it normal to see a pound or two weight gain as your eating food and becoming more active in the beginning? My surgery was 3/31/21 and I've lost 29 pounds, but up 1 pound this morning.

It really has nothing at all to do with what phase you are in - liquids, mushes, solids, etc., as the same general timing of loss progression happens even for those of us who never had a liquid phase. Do a search for the "three (or third) week stall" and you will see that most everyone has this problem at around this time.

The majority of the weight that we are losing initially is water weight as that is associated with the glycogen (basically carbohydrate stores) that we are burning at first. Once that is depleted, there is usually a pause, and often a pound or two of water weight moves around as your body attempts to restore some of its glycogen reserves as it moves into burning you fat reserves in the longer term. There may also be some hormonal effects that play into this as well, but this is completely normal. The important thing is your loss trend week to week and month to month (which will be declining overall, but usually at a decreasing rate over time.) Day to day, it's anyone's guess and often completely random as to what you might see on the scale, so don't sweat that.

I wouldn’t worry about a single day’s “gain.” It’s not a true gain, just one of those weird things our bodies do day to day. just stay the course and do all the things your clinic says to do. I know as I try to let go of my old way of thinking about my body, my initial reaction is to want to cut something out/restrict, but with WLS that doesn’t have to happen. Your body is still healing after a dramatic event.

weight loss is rarely linear. It'll go up and down - or like many of us, you'll lose it in a "stair step" pattern (lose a few lbs, stall for a week or two, lose a few more lbs, rinse and repeat). As long as the overall trend is down, you're good. Fluctuations are very normal - but if those are messing with your head, then just weigh yourself once a week so you're seeing trends rather than day-to-day fluctuations.
