Weigh after waking up and using the bathroom. If not needing to go, still weigh. In case of warm nights and dehydration, body fat reading can be off (higher) 'cause the body not being at it's natural water level. Possible to weigh, note that the estimated body fat can vary up to a few procent then, it's not possible when eating in moderation that the body fat has increased that much in a single day while being in deficit.
The body is more complex than calories in vs out. When weighing less, the body needs less energy (calories) to maintain or lose weight.
When exercising, weight can remain the same due muscles growing stronger, when loosing weight, most importantly that it comes from body fat. If the deficit is to high, since the body wants to survive, energy can be taken from muscles instead.
Keep a eye if body fat lowers, exercising stimulates the body to give up on body fat while providing enough protein, food.. during the day, so it doesn't think there's a food shortage and actually can hold onto body fat instead.
Eating protein (eggs, yoghurt, cheese,..) helps to prevent muscle loss and is used to repair the muscles.
Eating fruit (banana's, apples).. makes feeling fuller for longer including drinking water before eating, leading to automaticly eating less.
Try to get back in touch with your inner self:
- Eat when getting hungry, stop when feeling satisfied but not over full.
- Eating smaller portions throughout the day, when eating when over hungry can lead to eating more;
- Allow to eat everything you desire in moderation, forbidding a food, can lead to getting a craving and eating more/over;
- Eat what your body desires, is this what I want to eat or what my body truly needs?
Listening to your inner signals also helps to trust your body, when only eating while truly hungry also leads to eat less calories overall.
Its not the calories that count always but the food quality / quantity (nutritients it contains):
A chocolate bar and a piece of fruit (banana, apple) contains the same calories, though the fruit will let you stay longer satisfied while eating the chocolat bar, it's likely to be more hungry quicker and eating more, eating less calories automaticly.
When eating fruits, vegetables, proteins (in moderation), by not even counting calories, it's possible to eat a few hundred calories less automaticly and still loosing weight.
It's possible to track food while eating on instinct, but if not feeling hungry while the food plan says you can eat more, stop eating. Trust your inner self also (it knows the best when having eaten enough).

@randiL I weigh in once a week, on my day off. I feel like weighing in more may put more pressure on the day to come.
I use my WiiFit board as a scale, since it keeps a record of my weight and BMI information as well, but setting it up on a flat surface (no carpets) usually displays an accurate number.
As a personal recommendation, follow your food plan as a guide and make sure you write down your meals as soon as you are about to get them; this will prevent the moment where you are holding your food log and remembering how much you ate and underestimating amounts. I have a tiny notebook where I write down the meals and their weight, so when I'm ready to write them down, they are accurate.
Get a food scale and measure everything. Increase your water intake and find different sources or variations for the meals you love that won't take a hit on your caloric budget.
Have a rest day! Enjoy your food and don't miss out on the opportunity to eat different.
Good luck!
