Motherhood clothes

Can I ask you guys all a question when I had my first pregnancy I was probably at 14/16 size in pants and I bought larges and by the end of the second trimester/third trimester they did not fit I did buy a couple pants on Facebook market that are extra large and they feel like they fit now do you think if I bought 1X that they would fit my whole pregnancy? I am 215lbs and I have a large bottom. And my issue last time is my thighs got to big to fit in the larges. I am early in my pregnancy but there are some pants on Clarence and I would like to be prepared
