7 days DPO

So since Monday I started feeling nauseous not thinking much about it. I was cramping that day also so I figured it was just mid cycle cramping at the time I was 2 DPO. Well the nausea hasn’t got better. I went on a trip to California that day and I couldn’t handle being in the car. And now today I can’t even stand the smell of yogurt. I’m thinking I have a stomach bug going on since I haven’t been successful at TTC. But I don’t know anymore. I can’t even drive 15 minutes without getting nauseous.
