Scare of the centry.

So, this isnt a pregnancy test but i need answers and opinions! Ive been tracking my ovulation for about 6 months now and my cycle is never regular. I'm supposed to ovulate on the 10th and we have an at home insemination scheduled with our donor on that day, but today i tested and i got a positive. I tested again, got two negatives. Was the first test faulty or am i going crazy?
