Ovulation question

I use two apps.. Glow & another who both say my fertile window started on the 9th.. However one app says I was ovulating on Saturday... Did I have to have sex on Saturday to get pregnant? I had sex on the Friday and also on the Sunday so I have had it every other day!? Is this okay? It's my first month of ttc with the fiancé,but all this ovulation and charts is just over confusing... Thanks!
