TTC since Feb 2017

Hello everyone! Decided to tell my current never ending story =) I stopped taking My Yasmin BC in February of this year and have been TTC since then. Periods were normal even before BC and norm from February-June (menses from June 7-11 last). Ever since then, I've had no periods. I've taken preg tests intermittently those months and got negatives on all. Just yesterday, we noticed brownish-tan discharge when wiping; same small discharge overnight while working. Having small cramps (not overbearing, but more of a nuisance). Husband and I have been using this app for a few months now and we've logged every 3-4 days of baby making time 😄 I know it is TMI, but I've attached a picture of this discharge to gain input from anyone in this community who has had this before and what were the outcomes. Have an OBGYN appt in 2 weeks. Thanks in advance! 😃
