What is this sweet smelling Watery discharge?

It doesnt stink, it smells sweet, my last period started march 8, it doesnt have any constistency relating to any sign of infection/std. Ive been with ome person for the last 6.f years and I KNOW it cant be an std from him messing around, could be pregnant we dont use protection just the rhythm method, but I think its still too early to test
