Last year I had a miscarriage at 11 weeks.

Now that my husband and i are actively trying again (just a fortnight so far) i have noticed I have backache, lower abdominal pain and leg-aches. These feel a little like I have done a long run and are now painful & tired.
The abdominal and back-pain are similar to those i get during my menstrual cycle, however, that's not due to start for another 2 weeks.

I am possibly more aware of each ache and pain since last year, however, can any of you put my mind at ease?
Pregnancy, cyst ???

There is no bleeding.
