Can you feel tired straight away after 3 days of conception?

Answer 1

No. You will not experience any obvious pregnancy symptoms for 2-4 weeks after intercourse. Your body will not realize it is pregnant until implantation has occurred. Your first signs of pregnancy most commonly include missed period, tender/swollen breasts, change in color of the breasts, fatigue, nausea/vomiting, increased sense of smell, and weight gain.
