Pregnant?? Advice please

So, my ovulation date was either June 21st or 24th, and I did the baby dance on June 20th. I thought AF may have started July 2nd but it wasn't due until July 6. I had inconsistent, brown and pinkish bleeding on the 3rd and 4th and I haven't bleed since then. I've been experiencing early pregnancy symptoms much like with my first, such as fatigue, frequent urination, white CF, craving vinegar, irritability, and somewhat sore breasts. I took some tests and all the tests seem to either be negative or have an extremely faint line. I am also still breastfeeding my 10 month old son and did some research and found that with a high level of prolactin it can cause a false negative. I don't know how long I should wait to take another test or if I should just wait to see if AF pops up? Advice?
