When to test?

Karli
After possible conception how long to wait to test? Urine/blood? I went off the pill a month ago still no period! I have two apps tracking my cycle for the most part are about the same.. Glow says I should have been fertile Jan 27 and we did the deed that day.. Ovulation tests have been negative all month but I recently discovered I was doing them wrong time of the day 😒 I'm cramping and my back hurts but still no AF normally my boobs swell and hurt before AF but I'm not having that either!! I took preg test Wednesday it was negative and I also took a blood test which was negative.. Thinking maybe I tested too soon?? I'm going nuts for something to happen!
