now dont quote me on this but as faw as I know sperm lives for about 4 or 5 days but this is only girl sperm as male sperm lives for only a day or two but they are faster swimmers so if the eggs already there and waiting then they will get there 1st and you will have a boy but if you egg comes later by a day or two them it will be a girl if that makes ant sence at all lol

sounds like ov pains I find when we are trying for a baba I have very bad ov pain and boobs the 1st few cycles but eaises of after that.
