When do I BD

JM • 28 started TTC #baby 1 June 2016. 2 and half years 🌟
If I ovulate around cd16 when do I need to BD? I'm on cd 11 at the moment but BD on cd9 and cd10 as I'm away till tomorrow. But in them days we've BD I did have watery cm, that was clear and watery, and stretched between my fingers but wasn't ewcm as that comes on cd15-16. 
I'm back with my partner from tomorrow till sat. And hoping we can BD a few more nights. 
But what you ladies think?
