Pregnancy and Positive and Negative Tests

Ok... soo long story short.. I have a almost 1 year old and haven’t really been trying to have another one just yet, but i also havent been preventing it either... so, with that being said i have taken multiple tests, 3 came out a faint positive and the rest have been negative..... any pointers?? What should i do?? I have an appointment July 8th and im terrified.

Also, i have only had my IUD out since May 19th, bled for 3 days and haven’t had a period since.....
