13dpo BFN am I out

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I’m due for period today, my premom app says it’s due tomorrow. Should I just wait and see if AF comes? Or is 13dpo too late now and I’m out? 😞

Having a lot of discharge, some cramps on and off, no appetite and nausea sometimes, but I don’t feel pregnant and i also don’t feel like af is coming.

Anyone been there ?
