Hi Dawny,
I feel twinges in my 'doodahh' quite often. Sometimes it feels as though its coming from the left really low down and sometimes it feels as though its in my bone, if you know what I mean...right at the bottom. I suffered from that condition where your pelvis goes really soft during pregnancy and can be painful to walk or turn over in bed etc from quite early on. The docs say its down to hormonal changes. But I do feel it from time to time now, obviously not as painful but it sort of tells me 'im still here'
So, I think any twinges you may feel could be down to hormone changes or even

getting ready to show. I think as long as the 'twinges' are not painful then I shouldnt think you should worry, but if you want to set your mind at rest go see your doc.
Hope this helps.
