Pregnancy?: Depending on how long your cycles are, having sex on day 17 usually will not result in pregnancy, but if ovulation were delayed, and sex was unprotected pregnancy is possible. Your period was due normally on September 18 to 20 for a 28-30 day cycle time, so it is not "two weeks early if it occurred on the 12th of September. Implantation can cause bleeding: get a serum pregnancy test (HCG).
