No, not necassarily. You may have a gain in water weight but can be losing fat weight during your period.

If you are not eating enough - minimum 10 - 12 x your current weight in calories a day - your weight loss will slow. So it may be the lack of calories not the increase in carbs. How long did you increase your carbs for before you decided it stopped your weight. You have to give it at least a week. You also have to look at how your plan is working - not on a daily basis - but long term, say over a month.

Alcohol and sugar are a deadly combination for weight loss. Your body will burn alcohol, then carbohydrates, then your own fat for fuel. I couldn't find Strawberry Margarita anywhere, but I did find a listing for Libby's Strawberry Drink, which is probably similar. 11.5 oz. contains 56 grams of carbohydrates.
