confused and slightly concerned

So I just finished my period about 3-4 days ago and within those first could days I have had intercourse and have had pains in my private area which isn't new to me but then when I went to the restroom and went to wipe as I was done I had some spotting but a little extra if you know what I mean? Lol but I have never had this happen to me before and I don't want to start getting scared for no reason. So if anyone can give me some opinions or advice that would be great! And sorry for giving TMI! Lol
