Cycle day 35 no period and negative test

Hi girls, instead of getting my period this month I got a heavy white discharge, no smell or anything - it felt like getting my period but no blood. I've done a couple tests at day 1 and 5 of my missed period and both negatives... I've never ever missed a period and we have been ttc for the better part of this year.. I am so exhausted and grumpy plus my skin has broken out, I've been having odd dreams and waking up super hot... Could I be pregnant, when should I visit a doctor? I'm so nervous because we want a baby so bad...
