Cycle 3 days late

Had HSG on April 1, ovulated on April 12, cycle was due this Saturday. Had all the signs & symptoms that it was coming. It’s now 3 days late. Still bloated, sore breast etc. wiped today and had a little brown discharge. Sorry for TMI picture! Due to have colposcopy tomorrow. Negative pregnancy test. Would I be considered out for this month for being pregnant ? Anyone have brown discharge as such? Worried to have colposcopy with late cycle .
