I'm with Danni - my EWCM and DH's spermies look the same....i can't tell the difference, we just pretend that it's EW anyway and go again...LOL...

Your lutel phase is generally 14 days (however saying this, it does vary from woman to woman, but they say 14 as a rule of thumb). So i would suggest that you test after at least 14 days.....

I also agree with Tamara that the cramping and blood stained CM could be implantation, in which case you could try testing in about a weeks time...Good luck..
