Sir/mam me and my gf have unprotected sex on 21/12/17. And after 21 hours she takes a unwanted 72 pill. After 7 days later she have a period like blood flow and it lasts for 5 days. And it's actually same like normal periods. After that she don't get pregnant in next month. We are test pregnancy with a urine pregnancy test 7 times. But every time it shows negative. After that we are sex in 18 January with protection. After that we are sex again in 29 January but this time it was anal sex. But for safety she was taken a unwanted 72 within 1 hour. After 7 days she have a period like bleeding. And it's last for 6 days. And the flow is normal periods like flow. So sir/mam what is that? It's withdrawal bleeding or implantation bleeding? After that tomorrow my gf have abdominal pain on left side and today she have the lower abdomen pain in middle. Can a girl was pregnant if she have a withdrawal bleeding? And what is the pain? Can she will be pregnant? I am very.
