Ttc #7

I have six kids and me and my boyfriend are trying for another I've been doing the glow calendar for three months and last August I found out I was pregnant and at that time I was really depressed about it and didn't want it and i miscarried a week later and I became depressed knowing that wasn't the type of person I was in October of last year again I found out I was pregnant and this time I was very excited and everything was good I ate well exercised did everything I knew was right and at 14 weeks 5 days its carried again. Now we really want one and from this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> it says I have been ovulating for the past 7 days and we have had intercourse everyday for the past 16 days what are the odds that this may be a good thing and when should I test I'm supposed to start af on the 19
