Has anyone ever found out they were pregnant after getting a negative blood test? My cycles are usually 29-30 days and today is day 41. Not sure what's going on. I'm so confused. The last time I was late I was pregnant with my daughter and that was 7 years ago. I've taken 5 PG tests, all negative and went to the doctor yesterday for a blood test. Results also came back negative. Any advice would be great. Thanks!!!
