Hi there - I've tried BSF before, it didn't work for us in regards to conceiving BUT it did help with my PH. Also, for those with little or almost no CM, I've read before that taking Mucinex (with guaifenesin as it's ONLY active ingredient) 5 days before O helps increase CM. I tried it a couple of times when we were TTC and it helped GREATLY. We still didn't conceive but I think it's something we'll still try next time around.
