So my periods are always very regular. They're right on time with what the app predicts. My cycle is 28 days, my periods are about 4 days, I can feel even feel the day I'm ovulating. Like I've got it all down, the latest I've ever been is 2 days and that's only happened a hand full of times since I started having periods. So this month... At the time of my period I had nothing but brown discharge. The last day of what my period was supposed to be I had light red specks occasionally when I would wipe then nothing. It's two weeks now since my "period." I've taken 2 pregnancy tests, one the week I was supposed to get my period and then just a few days ago but they keep coming up negative. Has this happened to other people? Do I just need to wait longer to take a test? Or am I not pregnant and it's possibly something seriously wrong?
