Hae gals...quick question I’m 3days late according to the app I have been using for the pass 3 months and 1day late according to glow. Took two test today after work and both where negative. I have sore boobs, running to the bathroom 100x a day and night, heartburn and gas lol. No real signs of AF. Hubbie and I have been ttc for about 6 months since our MC in December. What is going on does anyone have an idea or is experiencing something similar??
