opinion:possible trigger still or possible bfp

So, I told my self in NO WAY was I going to pee on a stick until after my Exp. AF. Well, a POAS addict is a POAS addict, lol! I am guilty 😕 any who, I am on my second IUI (femara and ovidrel). I didn't test it out this month because I said I wasn't going to POAS. I obviously caved in. At approx around 10pm today I will be 13 days post trigger and I am 11 days post IUI. I got a pretty strong positive. This time last month I had tested it out and was showing what I believe to be BFN or made up very faint lines. so, if anybody has been through this have they seen a positive this dark from a trigger this late? or a BFP this early? My AF is expected Saturday and my blood test will be Monday. Thank you all for input. and i know with taking the trigger that I shouldn't get my hopes up!
