Last day of ovulation and my head hurts I'm nauseous and constipated and I have cramps like I'm on my period. Also super angry/weepy today for no reason. With the unprotected sex I had this time around it's possible my egg was fertilized. But I know you usually dont show any symptoms until it has implanted itself. This would be my second rodeo so I'm wondering if my body is feeling immediate hormone changes from the egg being fertilized?
