Possible pregnancy? Too early to test. What are these symptoms?

It is possible you could be some women do experience these types of symptoms and come to find out they are pregnant. BUT if its only been three weeks I would wait another week and if you dont start your period take a test I would use clearblue digital they are very accurate. I know you said your hopeful just dont get your hopes up it could be bad pms since your period was only 2 days instead of your usual 6 days but I wish you the best.....and why do people post rude comments when you just ask a question just ignore them ;)
