Anyone else thinking about maternity clothes already?

I'm only 7 weeks 3 days but my clothes are already uncomfortable and I only have a few shirts that I can wear. Friday I'm going to go shopping. I'm thinking about hitting the good will for maternity pants an idk maybe walmart for some bigger tops. I'm not very big to begin with I'm 5'5 and about 125 pounds right now but by the end of the day between eating and being gassy my jeans are so uncomfortable. I use a hairband but the button hurts. Anyone else feeling the same?
