What helped you get BFP

Alison

What guidance or product used do you feel resulted in your BFP after a long time of TTC? Was it Dr advice, pharmaceutical drugs, a product, testing devices, voo doo (just kidding, sort of).

Our backstory, we've been TTC for 2+ years with no success (not even a chemical preg). We have two children together, ages 14 and 12. I have very regular cycles (31 days), monthly positive OPK's, no existing conditions (that I'm aware of), neither of us drink or smoke, pelvic exam showed no blockages, sperm count/viscosity within normal ranges.
