Cycle day 59.

I am on cycle day 59, I have taken 3 hpt that have been faint positives, went to the doctor had a urine pregnancy done and it to,was a faint positive, but, they did blood work and it came back as a <1, which means NEGATIVE. Doctors are saying its either a false positive or chemical pregnancy, my period still has not come, and doesn't feel like its coming anytime soon, doctors said if it doesn't start within the next 2 weeks, I'm supposed to go in for retest. My question is, has anyone ever went through anything like this?
