hi everyone. I did the math and I'm currently 4 days into my 4 week. I've had tons of symptoms like sore ribs, fatigue, cramps, tingling in my hands, back pain, vaginal discharge, and some other things. I should have started my period on the 21st but no sign of it. I took a test this morning and it was negative. Is it just too early for the hormone to show up? When should I try another test?
