I KNEW I was pregnant for 4 weeks but the darn tests said otherwise. Judging by the U/S dating and when I felt the implant cramping I actually ovulated late and implanted even later. I knew something was up with my body and the cramping was definately implanting but seems my HCG levels were slow to multiply. The Dr said it's quite common when you ovulate late and definately agreed it was a late implant
HTH hun!
