Belly feels tight

Je

Hello ladies! I’m 25 and 4 with my first baby, and for the last two days my belly has felt very tight. I’ve tried looking it up but I can’t really find any solid information. Some articles say it’s just your skin and ligaments stretching others say Braxton Hicks or preterm labor. It’s not painful, but it’s pretty uncomfortable. Has anyone else experienced this or know of any remedies?
