What has everyone tried using as a sperm safe lubricant? We used preseed when we were ttc and became pregnant (also used OPKs) but unfortunately we just lost that baby on Wednesday. I'm trying not to assume preseed had anything to do with it, but from reading some reviews it's hard to not correlate it. Has anyone had success with anything else? Coconut oil? Olive oil? I plan on asking my OB at my 2 week follow up, but I always like to have first hand accounts from you ladies!
