spotting 21 days

Gyno wont see me unless AF doesnt show this month or if im spotting again. i started spotting April 4 & ended the 25. could that have been AF? i never needed more than a panty liner sometimes i didn't need one. It was more watery & pink or somethings globs of eggwhite cm with a little hint of pink nothing more than that. it didnt last all day either. sometimes id wipe it'd be nothing at all. anyone had anything like this? i dont think im pregnant. i took a test when i was spotting & it was negative. havent tested again since then..
