becki, even blood tests arent acurate these days. My sister, when she was pregnant, didnt show up on her bloodwork or urine sample untill 8 weeks pregnant, and thats quite common for alot of women. Im now over 20 days late and so stressed out that I might not ever be able to have kids, everywhere I look people are pregnant! its so frustrating. I read and have been told that you can mentally delay your period, and that due to travel sometimes its either late or doesnt arrive. I have travelled this month, abroad. So i wonder if it might have anything to do with that. Have you travelled anywhere? x
