Help!!!

I had a miscarriage in april I hadnt got a period since well last month on the 19th of may I did a hpt and it came out positive I actually did two they both came up. A week later on the 27th I did another and it came up positive and then I scheduled an appointment for the 11th which is this friday on june. I did another test today and it came up positive but not that dark as before but it was there is that okay. Im kind of worried now im wondering if maybe my hormone is dropping or maybe I didnt urinate long enough on it. What should I do. I also dont have many symptoms just like urinating frequently, blue veins on breasts and hunger thats about it. But I dont have morning sickness or anything else. What do you think am I or not. My appointment is friday but im very curious and am tired of waiting for that day.
