Protected and pulled out sex during fertile days. couple days later nausea and little discharge. am i pregnant or is it too early for symptoms?

Too early: Implantation, when the fertilized egg implants into the endometrium, happens about a week after ovulation (range: 6-12 days), and it takes another 3-4 days after implantation (9-16 days after ovulation) for the blood pregnancy test to first become positive, followed 2-3 days later by the early home pregnancy urine test. Nausea and morning sickness usually first occur 4-6 weeks into pregnancy.
