Ate, I can't see the photo you're referring to, but at 38 weeks pregnant, any unusual discharge or changes deserve a quick check from your OB, better safe than sorry! Is it colored, thick, or different from your normal discharge? A few of us mums have called our doctors just to describe things over the phone, and honestly they always prefer that you reach out. Please get in touch with your doctor or go to your birthing hospital kung may concerns ka, ha, you're so close na!
