Shettles method

Has anyone ever tried the shettles method? I’m the proudest and luckiest mammy of 3 beautiful healthy boys. I would love a girl so was toying with shettles method. I won’t mind boy or girl once I’m blessed but I think the want to try for a girl is interesting. I’m on month 4 of trying to conceive with no luck. I have no cervix due to 4 lettz treatments but have a lot of scar tissue. I’m wondering is it affecting me conceive? I’ve never struggled before. Baby making with boring positions and no orgasms is tough going and frustrating!! I mean boring as in no happy ending and no playing around or changing positions. I had a previous traumatic birth with no dilation, I went into shock. Baby was in icu and we were both badly bruised. Am I holding onto fear and stress about it? Anyone every tried shettles and succeeded? 🤍
