Preggers or overly hopeful?

So I was having ewcm on the 7-8th so we BD on the 8th and on the 10th. On the 14-15th I started to have super sore boobs, a little more tired, and my emotions are all over the damn place. Sore boobs has never been a symptom of AF for me and I don’t Remer hating it with my other two kiddos either. Am I symptom searching or is this good news?
