Loss of appetite?

I'm almost 9 weeks and I have recently lost my appetite. Like, completely lost it. I wasn't hungry but knew I had to eat so I ate maybe 4 mouthfuls of pasta. Normally I eat a whole bowl or more. I think about food and I'm just... not hungry. I always feel full. Not really nauseated that much. A little. But definitely not sick. I'm just wondering if this is normal?                           More symptoms I have (In case they're the cause of the loss of appetite lol) are:                   Constipated, irritable, tired, emotional, weak, bloated.
