Sounds promising... Right?

I'm terrified of getting my hopes up and being crushed. I'm moving in a day and I can't go to the doctor until I get to the new Army Base. I had two positive tests yesterday, one was FMU and one was SMU and then at like 4am this morning I had another positive. If it was a chemical, would I have had 3 positives? I know I should keep testing but tests are so expensive!! I'm not positive when AF is due.
