Ovulation

The glow app says my ovulation is today. But my discharge is creamy white. Last Saturday I had sex with my boyfriend. And a couple hours later I felt nauseous and had cramps. It held on for a few hours and after that I felt normal.

Could it be that my ovulation was earlier? We had sex on different days. That Friday I dreamed that I was with my boyfriend and walked to a woman who said to me that I was 6 weeks pregnant. That Saturday I felt nauseous and had cramps. And since then I dream a lot. Feeling nauseous sometimes, and have acne everywhere.
