Our first was a pleasant surprise, so can't help you with that one (and he was a boy). When we were TTC our next one we DTD every second day from CD14 till the end of the appearance of EWCM (I didn't really have much of an idea about my cycle at that point apart from it being 36days long, just knew that we should probably do it lots LOL) and we got pg first cycle and she was a girl. We did the same thing when TTC our 3rd and got another girl first cycle. On both of those times we weren't trying to gender sway at all. I have since realised however in the months before TTCing #4 when I paid close attention to my cycle that I don't O until the EWCM is gone and I get O pain about 2 days after it's gone. So when TTC #4, we didn't DTD till the EWCM was gone and as soon as I started getting O pain we DTD. We did it two nights in a row and we got a boy. We knew there wasn't any certain way of gender sawying but we thought we'd give it a shot and if it turned out in our favour great (as it did) but if it didn't then no drama. That's just how it worked out for us though.
