Why am I not losing weight?

I know it can be discouraging but as long as you entered all your stats on MFP, weigh/measure everything correctly, it will happen. I feel media has trained us to think we'll magically lose pounds every week but it realistically doesn't happen that way. Plus it's truly not healthy for us.
The weight stall could be lots of different things such as fluid retention, waste weight in your body, just your body adjusting as you go along. Some weeks you'll lose 1-2#, stay the same or gain weight. As long as you stay the course, it will change, keep looking at the big picture and not each loss/gain as a lose/win situation.
Patience and consistency is key, and keep up the good work!!

You know, when you've been sick last week then it's possible that your body still holds onto water due to healing. Give it time.
Also, if you're menstruating then your body will likely store more water at various points of your cycle, which is not bodyfat, but will mask weightloss. Some people report gaining up to 4lbs during menstruation or ovulation out of nowhere. Say you weigh once a week. You did everything correctly and your body lost 2lbs in fat. Then it's menstruation time and you gain 4lbs in water weight. Next day you step on the scale again and instead of seeing the 2lbs loss you worked so hard for you see you gained 2lbs! Eeeks!

Hey, we share a birthday! Happy b'day to us! 🎂
As stated above, patience and consistency is key. Sometimes the numbers on the scale don't move for what seems like forever. It's frustrating, but I like to look at all the other benefits healthy habits bring besides just weight loss.
When I was obese, I couldn't climb a single flight of stairs without breathing hard and needing a rest. My knees ached and I'd often ascend steps only with 'my good leg.' My blood pressure was borderline high and I was pre-diabetic.
I'm 85lb/6 stone lighter now. My blood pressure is text book perfect. I am no longer pre-diabetic and I can climb stairs with no problem. Daily 30 minute medium cardio workouts on a rebounder have melted away my saddlebags and re-shaped my lower body. All of those things have happened even when the scale didn't budge.
As for improving, I'd suggest amping up your daily walk by increasing your pace to where is it consistently challenging. Or maybe switch to a walking area where you can add a few stair steps or hills?
If you've just restarted MFP this week, give yourself time to get back into the groove. Hopefully the restart will come with an extra boost of motivation.

You actually currently do not know what your starting or current weight REALLY were. Well. You know what your weight was at a particular point in time last week when you were sick. And you know what your weight was at a particular point after your birthday (happy birthday, btw!)

What you don't know is whether any of these were an aberration because you weighed earlier or later in the day, had too much or too little coffee, or salt, or veggies that are still being processed in your gut, or water retention because of exercise, menstruation, local gravitational anomaly, or, or, or, or...

You COULD get yourself a weight trend app (or use a weight trend web site). You could then enter your weigh-ins and observe your weighted averaged results. The trend will have a tiny bit of a delay; but, it should more clearly show your progress (or lack of progress).

It usually takes a good 4 to 6 weeks before people can accurately assess whether their weight is changing approximately as intended... while too slow is not inspiring... too fast can be a health concern too! Somewhere in between... ALL GOOD!

I agree with this (more than I agree with the other answers). It's only been a week(-ish).

OP, it's unclear to me what your exact timeline is, or what the nature of the illness was. I can make a fair guess at the nature of a birthday. 😉

If your low weight last week was when you were sick, and especially if being sick involved something that involved eating less (or absorbing less, if - to be indelicate - having vomiting or diarrhea), then your weight last week may've been misleadingly on the low side. Or, if it involved normal eating, but inflammation or head/chest congestion, last week's weight could be misleadingly on the high side.

Even if you were reasonable on birthday calories, but the food involved more carbs (birthday cake?) or sodium/salt than usual - even if perfectly reasonable amounts of either/both - then water retention would increase above whatever pre-birthday baseline had been.

Bodies are weird. At this point, truly, you don't have enough data to know whether you're losing fat or not. (Scale weight is - for most of us - primarily water, then some combination of body fat, lean tissue, skeleton, food in our digestive system on its way to becoming waste, and several pounds of beneficial gut microbes that aren't even genetically "us" (they just live there)). Water and waste, in particular, tend to vary by several pounds within a day or across a few, and hide the fat changes on the bodyweight scale. Even fast fat loss is a few ounces per day, on average. Those things can play peek-a-boo on the bodyweight scale for a surprisingly long time.)

It's only been a week. Keep going until you have at least 4-6 weeks of personal experience data. (Compare body weight at the same relative point in two different menstrual cycles, if you're of that age.)

While you're waiting, if you haven't already done so, maybe read this very good article:
