Possible labor?

Hey all. 37+3 here. Had my son at 37+5.

I’ve been feeling light cramping that got semi heavier for the last 2ish hours. I have shortness of breathe for the last month due to this pregnancy /a bad injury right before the pregnancy.

Last time it was pretty clear cut that it was contractions. This time, my husband thinks it is but I’m not so sure. If so they’re pretty far apart. What are some signs I can look for?? No bloody show, and no water breaking yet obviously. I just feel so clueless lol
