Was going to name change for this as am bit embarrassed. There is a trillion zillion chance I may be pregnant. Highly unlikely as I have missed two periods completely (before we did the deed) and I am hitting menopause, hence my elderly age and the total shock it will be. How soon can I test, it's a week tomorrow before my period is supposed to arrive. Does First Response go back that far, the worry is killing me. Please help with any test ideas. Thanks
