I have tested positive for being pregnant, but since I have had an absence of my period for awhile due to it being irregular could it just be a fluke?

So here it goes...I have always had irregular periods, I tried birth control pills to take care of it but they only made me extremely sick. For the past year I have been under a fair amount of stress and I have not had a real period since July. I have taken pregnancy tests each month to make sure that I was not pregnant and until now they all turned up negative. Two weeks ago I took another test and it was a really light line on the test but it was positive, and it was with a test that is pretty reliable. I got worried so I went and bought two cheap tests and they turned up negative. Now today I took two early response pregnancy tests and they both came out positive. Can the fact that I havent had a period since July and havent had periods and tested negative up until now mean that the positive test result is a fluke? How rare are false positives? I am going to the doctor next week but I desperately need some insight right now because I am going a little crazy just wondering.

Hi!
False positive tests are quite common with urine ones, especially in cases of irregular cycles. A blood HCG estimation test would be most reliable. If the test is negative then you are not pregnant. If it is borderline, repeat after a week to see if the levels are rising. Rising levels indicate pregnancy. Take care!
