Need help

My husband and I have been trying for a little over 8 years now to have our first child! I had almost given up hope til last Saturday (June 11th) I took a test just for giggles. It was a faint positive but it was there! I re tested Sunday (June 12) and I got another faint positive! Figured the math up I would only be about 4 weeks along. I took another test this morning (June 17th) because my period still hadn’t came. It was negative. I don’t know what I need to do! Please has anyone ever been in my shoes?!
