Okay I’m 12DPO I ovulated on November 25th and I have 2 apps that I use to help me keep track. But one said I should have started AF on December 3rd. Glow says I should start AF today. But I haven’t had any signs of AF showing up. I’ve been having these symptoms since December 1st, indigestion, heartburn, gas, headaches, slight cramps, milky white discharge, nausea, fatigue, dizziness, and I’ve been having problems going to sleep at night. My nipples have been sensitive but my boobs themselves haven’t been sore till today. I’m so confused on if I’m pregnant or not. Here are the tests I have taken.
