Hello, my girlfriend and I are concerned she may be pregnant. Here are the hard facts: We had unprotected sex (July 4th) using withdrawal method. (Withdrawal was well before I ejaculated, which we planned.) Some sperm may have gotten into her vagina though.
She is showing no signs of pregnancy, e.g. no soreness in breasts, no fatigue, no constant desire/necessity to urinate, etc. But she has not had her period yet, and it is late by about 1-3 days.
She recently had oral surgery, around July 13th, with general anesthesia and antibiotics along with pain killers.
Her regular cycle is around 28 days, her last period was June 25th-27th.
