Did I miss my window? PLEASE HELP

Shaylyn • Our #1 is due in Janurary 💕
So my period was a bit longer than normal and also came late either due to the meds I was on or ... Idk really. Anyways I ovulation tested on day eleven and it was quite dark but since then the line has just been getting lighter. Can someone please help me ?!? Why is this happening ? 
Test on bottom - cycle day eleven 
Test in top - today (day 14 I believe)
