Up yet again!! Im 39+4 and the last few days iv had constant period type cramps and bad back, the cramps get stronger and then weaker. Changing position doesnt really help and theyre so inconsistent but so so painful!! Is it just braxton hicks!? I cant sleep more than an hour or so at a time which leaves me so drained and emotional and its starting to strain my relationship and i just don't know how much longer i can cope. God help me with the real thing coz im finding this painful enough. Sorry for long post just had to get it off my chest.
