You know, coming to a forum with an "am I pregnant?" question is about as unhelpful to anyone as it gets. I would never ask a group of women, no matter how many pregnancies combined they've gone through, if i'm pregnant instead of going to the doctor to find out.
There are many symptoms of pregnancy that can also be symptoms of stress or your mind playing tricks on you--especially if you've been trying for a long time. Nobody here can determine if anyone is pregnant just by the things you say.
You need to get tested and quit asking complete strangers who have no way of testing your blood or urine as is needed to determine whether or not you're pregnant. The only other way to guarantee that you are pregnant is to deliver the baby, and at that point, you are no longer pregnant.
Women, you should know that you need to be tested for this by a professional not a consensus. And men, just have your wives or girlfriends take a test. If you can't ask them to, then there is no reason you should have even put yourselves in a situation that could possibly create a child.
There are times that I am scared that i'm bringing a child into a world that would ask such stupid questions. And, yes, there is a such thing as a stupid question. You all who ask "am I pregnant?" to an online forum have just proved it to the rest of the world.
