Sillygirl...m/s could hit anytime, anywhere. It's crappy, but true. Consider yourself lucky that all you have had is a bit of n* from time to time. I would totally chalk it up to m/s. Sometimes, baby decides it doesn't like a certain food, one that you have been eating, than, BAM...no more of that for a while.
As for loss of symptoms, don't worry about it. Your symptoms will come and go and change all the time. Not everone gets EVERY symptom, and some women have none at all. If there are no major cramping, and no bleeding....you are just fine, and so is the little bean!!
Good luck!
