My stomach tenses up very frequently, but that was also a thing that happened to me pre pregnancy. I thought BH were much stronger than "minor" cramps?
Braxton Hicks is very definate and it is very early on in your pregnancy. I got BH around two week out from my due date. I did have that feeling just when my belly was growing it can be very uncomfortable. It also could be round ligament pain, that kind of feels like cramping too.
I got Braxton hicks starting around 6-7 months with both pregnancies. This sounds like bh to me although mine were completely painless...just very hard tightening. Warm baths also help.
Barely 2nd Tri here....and since before i knew we were pregnant i jave had a tight stomach. Doc says it's body adjusting. Cramping like pains that aren't severe and are infrequent she said were BH. I asked during 1st Tri and she said they can happen any time. It's body adjusting and preparing for labor.
