Ovulated april29, sex april30, blood only when I wipe may4, light cramping may5, period due may15, 6 days late but two negative pregnancy tests? Help!

Menstrual . Irregularities are not uncommon. If you did the tests correctly, and the test was negative 6 days after missed period, you are not likely to be pregnant. See this site for other signs of pregnancy, and if you have any signs, it may be time to see your doctor for a blood test and/or ultrasound exam. http://www.webmd.com/baby/guide/pregnancy-am-i-pregnant.
