I really do t want to test early. I hate getting my hopes up but with that being said the app says af is due the 20th. I have a doctor's appt the 19th that generally I have to have xrays done. so question is. do I test early and hope for at least a faint line? will the xray be dangerous that early if I am pregnant? I don't want to take any chances. really want our rainbow. any advise is appreciated. I hate to sound like an idiot just not real sure how that all works with the xray part and don't want to mess up any chances here.
