My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> Calendar says I ovulated October 12 to October 18.. my period is supposed to start on the 31st. I recently had sex on the 17th .. is <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> accurate? Was I ovulating at that time I had sex? Or am I ovulating right now because I feel a little crampy and my discharge is white and sticky ..
