Food... bleh

I am pregnant again after a miscarriage in late may. This pregnancy I have felt a lot better than the last one besides being exhausted all the time. Yesterday I went to a wedding shower and ate a cake pop. It was awesome until afterward I felt like I had had way too much sugar. Since then EVERYTHING to eat sounds horrible. Not really nauseous but more like heartburn and no appetite but I know I have to eat to feel better. I am only 6w5d so I knew the aversions and morning sickness might hit soon but I didn't think it would be like an on and off switch and an aversion to everything!
