How can i make Hubby understand?


I had a breakdown today. He kept telling me he couldn't see the line i could see so well. He made me feel delusional, crazy even. Saying i was taking too many tests and spending too much money. I only am POAS because im scared I wont catch it in time again. I have pcos, so whenever i miss a period its a big thing. I swear i got 2 faint lines today, ive already lost 1 child possibly 2 to miscarriage and im scared i wont catch it in time again, like i have in the past. What can i do to help him understand?
