Are These Contractions? 29 weeks 2 days

Jasmine

I got upset last week and experienced a contraction but didn’t know till my best friend told me . My belly got really tight and it was a little hard to breathe, once I sat down for a moment it subsided. Now today, I had another one that was more in my pelvic /lower abdomen area and (2pm) , and felt tightening again here before dinner ... Is this really happening? Or is it just growing pains to get bigger?
