Help!?!?!

My period is late 35 days! I took 4 pregnancy tests, 3 of them when it was 4 days late and 1 recently and they are negative. The only time it ever skipped like this was on my wedding month 3 years ago. I have a lot of discharge constantly especially recently. I stand there and it feels like my period started and i go to bathroom to check and its just a lot of clear and white discharge. Anyone ever have this? I don't have medical insurance right now but i am getting kind of worried that it hasn't started yet so might have to visit doctor for cash patients just thought I'd ask on here first. Btw we are trying to have a baby.
