15 days late

I’m 15 days late and have had a lot of clear watery discharge i haven’t had any cramps or anything like I’m going to start and DH have been TTC for like 5-6 months. I tested last week on Monday and it was negative I don’t know if I should retest or just wait it out.. my doctors telling me to just wait it out which is frustrating because I want to know what’s goin on with my body .
