Earliest signs?

Af not due till 10/22 I'm only 5 dpo we went at it like crazy as this is our first fertile week TTC. I have a weird pretty much odorless discharge that ive never had. It's not like the cloudy kind when you're horny . It was like almost yellow? What is this ? I am not really getting my hopes up that I will get pregnant this time around but this would ve my first so I have no clue what to expect. ( also been kinda moody like crying for a half hour because my phone won't stop autocorrecting ) and have like permanent munchies. TIA
