Helppp

Hi so long story short, my boyfriend and I have been trying to conceive for some months now. At least 4 months. According to this app and another app my period is about 43 days late. I took a pregnancy test november 24th and it was negative. My discharge has been varying soo much the past 40 days. One day it’ll be white the next day clear. Anyone have any idea what I should do? I keep feeling like my period is coming but then it doesn’t. I hate taking tests only because we want a baby so bad and when it’s negative it just breaks our hearts.
