First trimester weight gain

Megan

I am eight weeks pregnant with my first and have been much hungrier these last few weeks. I think I’m gaining more weight than I should. I have always been pretty thin so I’m thinking maybe that’s why? I feel like it’s too early to buy maternity clothes but my regular clothes are getting so uncomfortable.

Has this happened to anyone else? Should I just get maternity clothes now even though I don’t think I’m showing?
