We had been ttc for 4 months now but we had no luck,i was ovulating right on time and we were bding religiously on the days but still BFN.so i then read an article saying if you don't have sufficient ewcm theres very little chance of conception becoz the sperm wont survive!i wasnt so what i did was use real egg white(yes its gross but it works if dryness is your only problem)as suggested in place of preseed.it worked a charm i got a BFP at 9 dpo!!!so try it out ladies or preseed but be really careful with the egg white,look it up on google and it'll tell you how to do it properly and safely!!
