Hey so the glo app says I'm 3 days late for my period. My Fitbit tracker says I am one day late. I took a pregnancy test yesterday afternoon and it came out negative. What should I do and how long should I wait? I was planning on waiting until this weekend to possibly test again, morning this time. I've been feeling cramps here and there. Super bloated and gassy. And headaches. This would be my second pregnancy. Also have been crazy tired. Napping during the day.
