Hi my gfs first day of last period was on August 13, we had intercourse on sep 13, I m sure I did not ejaculate. She missed her period now, showing some signs of pregnancy, she had white vaginal discharge after two days. We did urine pregnancy test on sep 20 night and Sep 21 mrng all went negative. On Sep 21 we tested blood in a clinic. The lab assistant gave us a report it is not mentioning any thing about hcg, also the assistant told us it is negative. Note-she has irregular period some times
