Senior prom and pregnant

I was not going to go to my senior prom because I am currently 11 weeks pregnant, prom is in about 6 weeks.... I did not want to be judged and was very worried about not looking good because my bump is starting to grow.. but I’ve recently changed my mind because I do not care what anyone thinks anymore but I do not know where to find a good dress that will be flattering on a pregnant girl ....any suggestions
