So my period is now a week late, which is abnormal for me, my breasts have been sore for the last two weeks and I've had off and on cramping, different from my normal period cramps. I took two FRER tests a couple days before my period and thought they had the faintest line. I waited a couple more days till my period was due and took an .88 Walmart cheapie that came back negative. I've taken a couple more over the past few days, including one yesterday and they all say negative. Has anyone had problems getting a positive in this test when they really were pregnant? My doctor's office is super busy and I can't get in for a blood test for a while so I thought I'd see if anyone else has some experience...
