Trying to remain hopeful

My fiance and I have been TTC for almost 9 months now. I've tried almost everything. I can't even begin to describe what I feel even I take a test and it become negative..... I've never had morning sickness but I've been having really sore nipples and I don't even want to test because of many negatives. It breaks me down seeing all of the positive tests on here and here we are.,... Still trying. I've been off depo almost 6 months and I don't know what else to do
