Plus Size, 7 weeks and gaining fast

I had my first ultrasound this past Friday and everything looks good so far which is a blessing and a relief after a tubal pregnancy last year. But I’m already overweight, I have hypertension and my cravings are the worst.

I did the keto diet all of August and most of September and really tried to watch my intake after going back to a normal diet but naturally gained some bloat back.

But since about week 4 1/2 of my pregnancy I only crave the worst carbs and I’ve lost almost all my self control. My stomach is growing and I know it’s just fat and food at this point.

Help!

I asked my doctor for a calorie count per day and she seemed very hesitant to give me a number since she was just pleased I wasn’t dealing with any morning sickness but she finally said 1800. I don’t know how feasible that is considering all I want is carbs and more carbs.

Any suggestions or help would be much appreciated.
