Ovulation days...

Lilly • Mum to two girls.
So according to glow my peak day was yesterday (Friday) and another <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> I have, it is tomorrow (Sunday).
BD Thursday, yesterday, nothing yet today. Do you think it's best to be safe and BD today AND tomorrow? I have very mild cramping that I get when ovulating. I'm 19 and this is my first month TTC!!
