Very impatient... Ugh

Ok, so now that I am pregnant I am so happy!!! Yay! But it is killing me to know that everything is ok and I would love to know how far along I am!!! Ugh! Dr s Can't get me in until May 19th... That's weeks away from when I called and set up an appointment... I had a chemical last month and am still nervous about losing this one. But I tested again this morning ( a week between test) and it has a darker line... Also bc confused in how far along I might be... If I go by the last positive opk then I am 5 weeks and 3 days... But my lmp was on March 13th.... So that would put me at 7ish weeks... Does anyone have any advice... I am just very impatient with this... First pic of positive at 4 weeks, second pic at 5w 3d.
