the length of a cycle can vary from month to month so i don't know that anyone can confirm that a biochemical pregnancy has caused a delay in your period. if the egg has becomes fertilized hcg is produced and a home pregnancy test can detect it in your urine as soon as 6 days before a missed period. if you are trying to conceive purchase a home pregnancy testing kit. talk to the pharmacist since there are many available that have different sensitivities in detecting hcg. a fertilized egg not implanting into the endometrium could point to a luteal phase problem such as insufficient progesterone or problems with the uterine lining.
