Preg symptoms?

I’m one month 3 ttc (which I know isn’t a lot) and 10 dpo. First month that we BD’d at the “right” time, so I’m hopeful.

Having some weird symptoms that could be af, but have never been for me. I have backache for 3 days, light cramps and now tons of watery cm.

Anyone else have anything like this before bfp?
