Okay ladies I'm two days late. I've tested three times randomly since ovulation - twice with a 6 day early test and once with a cheap one. All three have been negative. How long should I give my period to show before I either test again or call my dr? It's my first month off birth control btw but even before I started taking the pill I was so regular I knew exactly when my period would start. I've also not had any period symptoms: sore boobs or cramping.
