Welcome Catherine. Give us some more information such as age, weight, amount you want to lose as well as a list of what you are eating. It will help us advise on your macros and stomach issues.
As far as weight loss goes, this way of eating helps repair years of damage to our bodies. While many people lose some initial water weight, most don’t see rapid weight loss in a mere 2.5 weeks. Your body may be adjusting in other ways first. There are many non scale changes such as losing inches but not weight, sleeping better, mental clarity, decreased inflammation, etc. Do a search for NSV (non-scale victories).
It takes weeks to months to become fully fat adapted. Some people lose quite slowly or don’t see the scale move for weeks, until it finally does. It’s a long game and many are using this way of eating to reverse the damage of years of bad eating and while losing weight is a great side effect, it’s not the only reason to do it. You may find your cholesterol numbers improve even though you are eating what seems like too much fat. Here’s a link to the cholesterol sub forum: https://www.ketogenicforums.com/c/health/cholesterol
Here’s some newbie information you may find useful:
Keto is this easy (Keto for beloved noobs)
This is for Phase One - the starter phase. It’s still not complicated later, but this is the really easy to explain version which will help you no end.
- Eat under 20g of carbs a day
- Don’t worry about the scale
- Eat plenty of good food - fat and protein - while adhering to 20g/carbs/day. Don’t worry too much about macros and calories EXCEPT carbs. Keep them below 20g/day. (Prioritize the protein - always start with protein in every meal, but don’t panic about it.) Your job is to get fat-adapted, so give your body the fuel you want it to use. Also, your appetite will vary - it’ll disappear, then it’ll come roaring back. Happens to most people, don’t sweat it.
- ELECTROLYTES/SALT - KEEP THEM UP
- Buy the meat you can afford - don’t stress about grass-fed, organic (con), etc… The worst meat is better than the best bread.
- Fasting is a tool. Nothing more, nothing less. Works for lots, not for others. Don’t let tools tell you to use it before you’re fat-adapted and it makes sense.
- This site has a search function (magnifying glass at the top of the page) and a newbies section - use them both, you’ll get a better variety of answers to your questions far more quickly that way. SERIOUSLY, THIS IS VERY USEFUL.[1]
That’s as difficult as it needs to be for a couple of months.
My good friend Terence (being friends with a Kiwi feels kinda dirty, but there you have it, keto makes for strange bedfellows) tells me this thing I have described above is called “dirty keto.” So yeah, do dirty keto, kids! 
Lots of Love, THE JUICE
[1]If you can’t find a useful answer after searching and reading for a while, we can help you a lot more if you tell us relevant data about yourself such as your reasons for doing keto, your weight/height/age/gender, a sample menu plan & any relevant health conditions.
