My DS6 is a product of artificial insemination (sort of). We were on our 5th try of this (insurance paid for 6 tries). I went in to check the eggs (I had 6 eggs) and to do the insemination. Well, turns out I had already ovulated so we decided not to waste one of my tries that insurance would pay for to go ahead with the insemination. Well, turns out that is the month I got pregnant. (After 2-1/2 years of trying). Boy, was hubby nervous at the first ultrasound - just thinking that there could have been 6 babies... My DD4 was conceived naturally after only 3 months of trying.
