Period like cramps at 25 weeks

Unique • Baby #2 11-3-23 ❤️

Hello all, so on Sunday my baby felt really low and every step I took hurt and I was also cramping and having bad back pain for most of the day. Yesterday was okay not in too much pain. Today the cramps in my stomach came back and I’m feeling pain in my lower back and butt. Should I be concerned? Is this normal ? I am a FTM
