Hi knowledgeable ladies

Just wanted to know if it is normal to go off your food? I have not been really hungry lately, im wondering if it is a sign that i could be 'getting ready' for labour? I am 34 weeks 4 days today. I cooked dinner last night and only had a sausage, i felt sick after that. This morn i am forcing myself to have toast. I am waking with AF type pains (had them for days).

TIA Jenni
