Anyone know what this means?

So my fiancé and I are TTC and we've been trying for a little over 3 months. I ended my period 3 days ago. I didn't bleed yesterday morning/afternoon or the day before that at all! Me and my fiance had sex yesterday because my discharge looked like I may have been in my fertile stage so he came in me. Right after sex I started bleeding and it didn't stop until this morning. When I woke up I wiped and the blood was a brown color. Could I have possibly conceived?
