Hey. This is my third pregnancy. I'm 6 weeks today. Since yesterday I've been getting lower back pain and tightenings that honestly feel like Braxton Hicks, no pattern but fairly regular. I should add I had a horrific time with my second and had horrendous back labor. Since then whenever I get any kind of cramp (period, upset tummy) I feel it in my back. Sound normal? No bleeding at all. It's driving me mad.
