Symptoms can come and go! Don't buy into the idea that no symptoms means something is wrong. You could always have your HCG levels tested to see if they are rising.
After my m/c, I would deliberately hold off eating as long as possible to see if I'd get nauseous. I do not recommend that, but I'm just saying I know how you feel!!!
Mine went away too. Bu then came back every so often.. But mine went away later than that... and so far everything is fine with me. good luck
I have no morning sickness.. just a dizzy spell here and there..and everything is fine...! dont worry so much!
