According to each <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> I have, the past couple days and the next week are supposed to be my most fertile time period. So, two days ago I took my first ovulation test: no LH surge detected. Took a second one today: same result. I suppose this answers my life-long fertility question, I don't ovulate. 😕
