Labor? BH? Contractions

I’ve had a few Braxton Hicks contractions so I know for me they feel like my stomach is tightening a little and it feels more like gas pains then menstrual cramps. They are usually random also. This morning around 5am I woke up to my belly being very uncomfortable. I had that same gas pain feeling and my stomach was rock hard. I kept trying to time them because it seemed like it would relax a little and then start again. It would last around 45sec, lighten up and start again a few mins later. This happened for around 45mins and then I managed to just try and relax and go back to sleep. I told myself that if it was labor I probably would’ve been in more pain and not able to fall back asleep. I’ve felt it slightly (but more like BH) a couple times today. What could it have been early this morning though? I thought BH weren’t consistent and these most definitely were. TMI warning... I also had the urge for a BM this morning while I was having these pains and it was loose and I felt a bit nauseous. I don’t know if this is a sign that labor is around the corner or if it was just BH that had a pattern that I was able to time. I was very close to waking my husband because it wasn’t a familiar feeling but was trying not to go to L&D and them make me feel dumb if it wasn’t a concern..
