Been trying to conceive with boyfriend for about a year now and haven't got anywhere but I am having symptoms of pregnancy and don't know if they are symptoms or just my mind being evil. If I am preg I'm 3 weeks and have sore breasts and cramps in my tummy like a stabbing feeling. I am also very tired and can barely stay awake for a 4 hour shift at work. Am I pregnant or just wishful thinking??? Xxx
