In all likelihood, two blue lines on an Equaline pregnancy test mean that you are pregnant. Generally, one line is the test line and one line is the control line. The control line will always show up if you have performed the test correctly, whereas the test line will only appear if a sufficient amount of hCG - human chorionic gonadotropin (the hormone excreted when implantation has occurred) - is detected.
Remember that a pregnancy that is detected early needs to be followed-up quickly by your ob/gyn, both to ensure that the pregnancy is in fact developing and to guarantee that you begin to receive prenatal care as soon as possible. Early prenatal care is an important factor in the health of your developing baby!
In addition to prescribing prenatal vitamins, your doctor is likely to recommend several blood tests, including ones to detect whether you have sexually transmitted diseases, CMV, and sufficient antibodies against rubella. Good luck with your pregnancy!
