Preseed...going to give it a go.

So, while shopping at CVS today I bought some preseed. At this point I'm willing to try almost anything to help us concieve (as long as it's safe and doesn't break the bank). I've heard it's a little messy so I'm apprehensive about that aspect. Has anyone had experience with preseed? Any luck getting a BFP using it? I'm hoping it will help since I don't ever produce EWCM (mine seems to be watery and thin around ovulation). Thanks for the feedback!
