Sorry to hear you aren't feeling well.

I'm onto my third pregnancy and I found at first it was a lot harder than what I remember, plus I'm 7 years older this time around. The first tri was the most difficult with the tiredness and especially that leg thing that you describe...argh, it's awful. I was up so much at night. I have older children so it makes things very easy in the sense I can fall asleep on the couch and they leave me and are even quiet.

I also found instead of feeling heaps better at the beginning of 2nd tri like I used to, it took till about 20 weeks before my energy levels came back.

Just rest and it will improve soon, hopefully around 12-14 weeks for you when it usually does when the placenta takes over. Make sure you rest up, that's what I did and it really helped me cope.
