I'm 13 weeks today and have been so so uncomfortable in my clothes, especially starting today. I've only gained 4lbs max in the first trimester, but I can't tell if I'm super bloated or my bump is showing up, or both. I can't button my pants and my bra is super tight. Anyone else growing out of their clothes at or before 13 weeks? Not sure if I'm getting big too fast or if this is normal for how far along I am.
