Achey buttocks/legs/ lower back 7 weeks, normal? I can't remember!

[mrswee]

I'm 7 weeks tomorrow (I think) today Ive have really achey buttocks and legs really starting at my lower back and all the way down to my feet in the style of the kind of pains you might get before your period.
I'm feeling rubbish as I have a cold and I'm still at work now at 8pm..
I've tried to look it up but everything is just about adominal cramps which i haven't really been getting or getting so very mildly this time around compared to last as I guess everything is stretched already.
This is my second and I just can't remember if I had this the first time or if it is normal... I've probably been sitting on my bum too long and should just take paracetomol and stop worrying.
what do you think?

I am 6 weeks and I have had a dull ache in my lower back on-and-off ever since the day before I got my BFP (ie 2 weeks ago).

Was worried for the first few days that it was a sign of something ominous, but everything seems to be fine, and the ache is still there, so I am just ignoring it! I think I read somewhere that a dull backache can just be a random first trimester symptom? I guess as long as you don't have bleeding, it's nothing to worry about :)

I reckon you are right, it's just coupled with feeling rubbish because of this cold and general pregnancy exhaustion (a good sign) and sitting on my sore ass for hours and hours!
