Trying To Conceive K posts 32K Orl. We have been trying to get pregnant for 5 cycles now and Orap knew everyone talked about how lube is bad and so is saliva and then tonight it finally dawned on me The past 2 months we have had sex every 2 days or more and done everything right but still no BFP. However we do more often then not have oral sex before hand I'm wondering if this is the problem, could oral sex and saliva really be that big of an issue while ttc? Needless to say this month there will be none lol! Oldest Newest 15 Posts.
