So confused...

So I haven't gotten my period but keep getting negative pt's. been ttc for a little over a year. this happened once before and it ended up being a burst cyst in my ovary only difference is a few weeks ago I had brown discharge for like 4 or 5 days off and on. only time I get discharge is right after my period never at any other time. Now I have a lot of whiteish discharge. my bff says I'm prego but the negatives have me confused. I'm using these sold on Amazon and I'm wondering if they're faulty. what do you think? am I preggo or is my body just going crazy???? I hope I'm pregnant 😔😔😔
