What is this??

So my husband and I are in our first month of TTC... according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation apps</a> I am in my fertile days now but I have never really had a normal cycle. I was put in Provera in May to help jump start my period since I hadn't had one since February. My period was from May 20-28. Fertile days according to my apps are Jun 5-10. Took an ovulation test yesterday and today and both show high. But as of yesterday afternoon I had this light pink/brown discharge when I go to wipe. Not enough to get on my underwear, just there when I'm

myself. Since I'm new at TTC I have no idea what it is... can someone help??

*update: definitely not my period. only lasted for about a day and a half.
