Queezy

So. I'm very confused. I just had a miscarriage like 6weeks ago. (Was not sick at all during- and I'm not stressed out. Just hopeful to try again) Haven't yet had a period since. But I've been feeling so sick to my stomach lately...queezy. Making me super thirsty and smell of foods making me nauseous. Do you think it's a belly bug? No fever.. I don't think I could be prego yet....?.... any ideas???
