NO AF and A big fat negative!

Anna
So I am usually regular and on time with AF, well March came and went no AF, I have taken several hpt bc of no AF and still negative! Im tempted to buy the digital ones that tell you the weeks pregnant (if you are) but I don't want to get my hopes up :( Send baby dust our way, it's been a year our daughter passed away and we are trying to conceive :)
