**lurking** I used to frequent this board and on cycle 19 we finally tried preseed for the first time....that was the cycle we finally got pregnant! I am not saying that it is a miracle worker- but it did work for us that month. I used it when BDing the 2 days before, the day of, and the day after ovulation.
I think by "sterile" they mean to use only the packaged applicators so that you are not introducing any bacteria inside of you (and to only use them once then throw away). I filled it to the 2 each time- which seemed like a lot, but I figured it couldn't hurt. Good luck!!
**I also wanted to say hello to all you other fabulous ladies!!!! I lurk this board every day and cannot wait for all of you to be posting in the DDCs!!!**
