Weird discharge

So I had sex 5 days ago with out a condom and he didn’t cum at all. I was very wet during sex and I had little to no discharge afterwards. 1) I’m scared that there is a chance I’m pregnet from precum. 2) I was about to take a shower and a very watery clearish white liquid came out of me- not the texture of my regular discharge. Does anyone know what this is. ( I’m supposed to get my period tomorrow and am on no BC)
