BFN at 8dpo so I'll get back to insanity ex.

I tested this morning and came out single line. Frustrating!! It's been my 4th month ttc and now testing is traumatic since it all came out negative lol. When we tried with our first baby just a month and she came. Second seemed to take 48 years. I need to stretch my patience to nth power. Better luck next and next and next month. Do you guys think still have a chance for the test to come out positive before the month ends? I so feel i am preggy or its just in my mind lol. I'll get crazy soon.
