Okay .. Ive been rrying to have a baby again i have two ive been trying for four yearsno luck possible. Why is that and i have sex on ny fertile days and all of the above but no pregnancy . well today i had cramps and back pains and this is two days after my ovulation and ive been havin white mucus maybe because of ovulation every month but no luck.  Why is that .. And ive use the pree seed method and i dknt think it works . we just used preseed last time we had sex a week ago .. Befor and after .. Could my cramps and back pains mean pregnancy .
