Overweight and pregnant fears

So i started at 281 im now 283 of course im 5-6 weeks pregnant now. But ive always had normal cycles and maybe im just scared that'll effect things. Im not overweight in a bad way just curvy, but any weight high is a bad weight to me ( no offense to any other ) i just really need comfort in the situation. My ultrasound isn't until Nov 27. and thats taking alot for me to keep calm and avoid the thoughts. I haven't had any weird symptoms. Cramping from time to time not consistent or all day evedyday just random and not severe.
