I doesn't seem that you are pregnant, but this conclusion must first be verified via home pregnancy test. If the test is positive, you are pregnant; if the test is negative, you are not pregnant. If you are not pregnant then may be experiencing a hormonally active ovarian cyst. Hormonally active ovarian cysts are created when a follicle doesn’t ovulate but, instead, develops iinto a cyst. The cyst in turn produces estrogen that stimulates the endometrium to grow and delays menstruation (period). But this can’t go on forever. The follicular cyst degenerates in time and produces less estrogen. A decrease in the estrogen levels lead to endometrial degeneration and desquamation. This manifests with spotting. This type of bleeding usually lasts longer, looks different and is heavier than a normal period. An infection may be present (or not), independent of delayed menstruation. To follow up, you can consult your gynecologist and request diagnostic procedures for identifying a possible hormonally active ovarian cyst and/or a gential infection.
