Help!

I am 8-9 dpo & have cramping and sharp twinges on my right lower side. The pain has remained constant all day and I’m now starting to feel backaches and a little sciatica pain in my right leg. My breasts/nipples are also a little tender to the touch with some watery CM. Anyone experienced this and got a BFP? When do i start to test after having these signs?

This will be our 4th month TTC & I’ve never had this before! Help!
