Soooo.... I've had really bad lower back ache for 24 hours now. I usually do get a twinge for about 3 hours at the very start of my period but not this strong. I'm moving around like an old lady, not ideal with a lively 2yo!
I POAS this morning and BFN, but I have irregular cycles and so I'm not entirely sure when AF is due - sometime in the next 3 weeks I think 
Also feeling a bit bloated and sicky but that could also be my imagination and/or PMT. Gah!
Can back ache be a symptom of early pg? Or am I being over-optimistic, and it's just AF being particularly mean this month?
