Testing out HCG Trigger Ovidrel. Wed Dec 05, 2012 6:01 pm. Hello ladies I an new here, but I have been using your stories and guidance for years..thank you. I took ovidrel 12 days ago and started testing a week after my shot, my plan was to test it out so I would know when I could trust a bfp result. However, I never got a neg test ( I am not sure if you can tell but the 9 & 10 dpt tests have very faint lines) and now they are becoming darker.
