So my period is 6 days late, it was supposed to arrive January 31. I did test on that same day and the day after and they both came back negative. I have no symptoms other than headaches and backaches. Not sure what to do, I don’t want to buy another test and see another negative, it’s just too disappointing 😞 in need of some advice please!
