I have used just about everything LC has for sale, hahaha - I'm a TTC tragic!
OPK's don't work very well for me, mainly because I can't test at the right time due to work. So I ditched them.

We use preseed sometimes around O.

We used the swimmer test and it was easy and worth the $$ for us because our GP probably wouldn't have sent DH for a test as we have only been TTC for 5 months, and also its a pretty confronting thing for a guy to have to do!! He still felt wierd about it at home, lol. When you get the kit with the funnel and the test tubes etc you'll see what I mean - there's nothing sexy about it!!!

I don't know about the reliability of the LC HPTs...they keep giving me a BFN! Haha just kidding, the LC HPT's are pretty good too from all reports.
