38 day of cycle

Nancy

So today is my 38 day of cycle. I started spotting on and off on Tuesday so I thought ok great my period us coming...but here I am 2 days later and still no period. My spotting is very light. I had a blood test on Monday and came back negative. I'm staying positive that it will come soon or that I am pregnant. Please pray for us to conceive soon.

But what are the odds of being pregnant if the blood test didn't pick it up or why am I spotting and no period.
