Help.....

Okay momma’s I need help so I’m on day 38 I haven’t started my period I haven’t had any symptoms that I’m going to start my period like no cramps, my boobs don’t hurt, and I don’t have heartburn which I usually do before I start, the past couple days I’ve had clear watery/sticky discharge and now there bits and pieces of pinkish color in it. I’m confused whether or not this is just me about to start my period of what. Idk if I should call my obgyn or not
