Contractions?

I have had a very bad stressful day and it ended with crying. It’s all a long story but the reason I’m posting this is due to the fact I feel my stomach tightening every couple minutes or so, I can’t tell if it’s just my baby stretching out my tummy or I’m having mini contractions. My belly hurts like a exhaustion ache from having such a bad stressful day..
