Okay so I've heard mixed things about your cervix during your fertile window. Mine currently is med, soft, and open like I can fit the tip of my finger in? (Sorry tmi) I'm supposedly on day 3 of my fertile period. So I've heard that's approaching your period, or its optimal ovulation?. I just ended my period so what do you ladies think?
