My husband and I have been trying to get pregnant for a couple months now. We have sex all the time and I especially make sure to have sex during my fertile week before and on my ovulation day. I'm using 2 different <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> to keep track of my period and when my projected ovulation date is. Why isn't it happening yet? What can I do to make it happen?
