Tmi Discharge fertile window help !

Tonya
Okay so I've never done this before I'm TTC #1 and I started my period on July 7 and was off July 11 my period is a normal cycle , well I've been off my period for 5 days now and today was my first day in my fertile window this month , me and my fiance had intercourse on the 14th , on the 15th I woke up and went to the br and when I whipped I had some discharge it was kinda brownish like dry blood well today the 16th I went to the br and after I whipped it did it again I discharged and the same color just a lil lighter , what does this mean ? I've never done this before should I be worried ? Is it normal ?
