Hi Bushberry14 and welcome. My total loss on an 8 week plan was 13lbs. When you read of people losing that in a week it is often because they have it to lose. As Sunny says we dont know all the facts but for me the most important thing for weight loss is keeping the carbs low and 50g I my ideal too. Depends what those carbs are because as soon as I add say a slice of bread (just one slice) the fluid gathering can put the weight straight back on. If you keep going you will start to lose again. On the subject of PCOS it is possible it is holding you back a bit as you are known to gain with PCOS so it might be harder to lose.
One piece of advice when I am stuck is to stop eating after say 7.30pm and not eat again until 10.30am or lunchtime if you can make it. It encourages your body to turn to fat burning when it has used up the glucose calories. Good luck and keep going.
