I'm in my TWW. Normally I have every symptom that makes you think pregnancy but it is really the same symptoms for pms. (Sore boobs, heightened sense of smell) This tww I began feeling exhausted. Four the past four days I've been extremely tired. This is very unusual for me. I thought perhaps I was over exerting myself at work, so today on my day off I discovered that I'm still just as exhausted. I hope it is pregnancy....but I don't want to be heartbroken
