Pink & light brown discharge after sex

Ka

My husband and I had sex last night (twice). Afterwards and all of today every time I wipe there is pink and/or light brown discharge. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> predicted my ovulation was last week. I’m hearing mixed things. From early sign of pregnancy to early period coming on but I’m not supposed to start for another 2 weeks! Help!
