We had sex 2 - 3 weeks after her last menstruation and she had them irregularly. She took Nordette as ECP 18 hours after. 6 days after the dose, she bled heavily lasting for 3 days. She also had abdominal pains then and she said it was just like her period. I'm not sure exactly if it is her period or just the withdrawal bleeding.
Was that a sign that she's not pregnant?
