Depressed i guess 😐😐

Hi ladies. Well lately im getting very i guess you can call it depressed, upset, unpatient. Like i keep mantioning in every topic, i have pcos. I have been trying to conceive for 8 months naturally and 1 month with metformin which makes it 9 months. I have always had irregular cycles, but i noticed since december or 2014 my cycles were kind of getting normal, at least thats what i though. Well i started metformin on february 2nd and according to Glow i was supposed to get my period the 7th if march but nothing yet. On the 6th and 7th of march I had some brownish and pinkish/redish bleeding just a tinybit when i whiped, but I am so chickened out to take a test. And that is just making me feel si depressed and unpatient. I want to test but my instincts tell me bot to do it because of my fear of getting a negative, and thats going to make me feel worst. These past few days ive been just crying and saying to myself why is this happening. This morning i woke up feeling down, and am ending the night the same way.
