I'm 33+1 and I'm trying to figure out if I'm having braxton hicks or contractions... I'm in a lot of pain on the right side of my tummy and in my lower back but it only happens every 10 minutes or so and the tightening last about 5 minutes or so. I know braxton hicks are not suppose to hurt or maybe they do? Scared of preterm labor but need to know if I should worry. It happened 3 times already.
