Having contractions (I think?) And my husband is horrified

I am exactly 37 weeks today, I've been sitting in an armchair for a bit after dinner and have been feeling streching in my belly, as if the baby is turning sideways and pushing out on my uterus. Or as if Im flexing my abs involuntarily. But I kind of clued in that it dosent make a lot of sense, and also felt around and when the feeling comes my entire belly is hard. But it dosent hurt at all.

So Ive been timing it and I think Im having contractions that last about a minute each but are anywhere from 6 to 15 minutes apart and do not hurt at all so Im thinking its nothing to worry about. Ive had 6 in the last hour.

My husband looked over at me midway through one and was like "are you just sitting there playing with your belly?"

I pulled my shirt up and showed him my belly and was said "no I think Im having contractions, Im timing them". My belly was super tight and weird looking and he just looked at it like 😲😲😲😲

I almost peed myself laughing 😂

I am going to call L&D and make sure there is nothing to worry about, but I thought I would ask here; do these sound like super mild contractions or..? Is there anything I should be worried about? I drank some water and am resting to try and settle them down.

*edit* L & D said to just wait it out at home, I mostly just wanted to make sure I wasnt too early if it did progress to labour. I was contracting about every 5 mins, lasting 50-120 seconds. I went to bed and when I woke up in the morning they had stopped. pregnancy is a funny thing!
