Unless you chart and know your ovulation date, then it is possible that you ovulated late (even if it's never happened before) and this would be a longer cycle whether or not you conceived. It is also possible that you conceived but your hCG levels haven't risen enough to register on a test yet. Some women tend to have much lower hCG levels in their urine than others and will not test positive on a urine test for several weeks. If that were the case than a blood hCG would be necessary to confirm pregnancy.
