39 weeks & 1 day

I have been experiencing some very uncomfortable feelings for the past week or so now but brushed them off because I thought it was just where the baby was laying awkwardly. My entire uterus tightens to rock solid and I get intense back pain along with this, this happens a few times a day nothing too regular but does stop me in my tracks if I am talking or doing something. After another DS member posted asking for some advice on exactly the same feelings I have been getting I found out from the responses these are braxton hicks and was completely oblivious to the fact that they could be BH. It didn't even enter my mind thats what it could be. Well all day today and yesterday I have had constant dull lower back ache which only gets intense with the uterine tightenings. I just cannot get over the fact that BH didn't occur to me. How did I not realise? I am well aware of what to look out for with BH as I have been watching out for them. Very odd.
