Gee it sure sounds like being pregnant is a big possibility, I don't think it is thryroid trouble, my mother has had both under-active and over-active and believe me , one can be very sick, you soon know something is not right.

Sounds like it would be nice if you were, and something you would indeed be happy about, just have to wait until you can get an accurate test done and see.

Just remember if you are eating for two, ends up with the result you look like two people after it all, in other words getting the weight off again is no easy going my friend.

Good luck, keep us posted how you are ok.
