Still no AF.. 3 DAYS LATE!

Katie • It’s always been hard for us to get pregnant, so here I am again trying for baby #2.
AF was due Christmas <a href="">eve</a>, still no sign! Just mild cramping. Any ladies have a negative with no period but test at a later date and get a positive because getting pregnant later in your cycle? I'm still not testing until tomorrow but nervous we didn't get pregnant until after glows ovulation prediction.. & worried about a false negative.. Ugh!! Getting pregnant has made me a worrier times 1000!
