my symptoms only really kicked in properly in th last probably 2 weeks (i am 8 1/2 weeks). i was constipated before then for 3 weeks... but that has eased down now and i just have the usual

slight morning sickness, tired by the afternoon (im not dragging myself to bed yet either) twinges and pains sometimes and my bbs are really sore now like heaps sore....

I didnt get the metallic taste in your mouth like some people have, my smell is still faily strong tho.

I would say if it is gonna happen it will soon.. a friend of mine only started getting the symptoms last week and she is 7 1/2 weeks.
