I have been spotting throughout December. I spotted on the 5-6. Then I spotted on the day of my period on the 22-23 than again on the 25. I took A hpt on the 23 One day after my missed period I got a neg. now it's 5 days after missed Af. I been taking more naps let my bf tell it. My lower back been hurting mildly. My af been regular since I been on @metformin for 5 months. Should I retest on the 28/31 or just wait to until Jan 22 a month later for af.
