Using lube while TTC?

Michelle • 30. Married. TTC baby #1 since Sep 2014. Miscarriage in March 2015 and CP in Nov 2015. Waiting for my rainbow...
I've been TTC for 4 months now, and I recently heard that most lubes interfere with sperm and make it more difficult to get pregnant. I immediately stopped using lube.  Has anyone else heard this???
