Hi Emma
I know exactely how you feel im going though the exact same thing at the moment.
Best thing you can do is to take the test...I know its a hard I think when your in a situation like this, Desperatly trying for a baby, taking the test to find out if your pregnant is one of the hardest things. Bottom line....You need to know! Its been almost 4 days since your peroid was due so you can go ahead and test. Dont be putting yourself down thinking that your imagining it all, you might just be pregnant. Believe me stressing yourself out about it is'nt going to make it any easier, be positive. Take a deep breath take the test & good luck hunny xxxx
