I’m pregnant ❤️

So my last period was on 16th March but I’ve logged from last period i downloaded a <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> says I’m 5 weeks and my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> say I’m 6+1! I did a clear blue test and that says pregnant 3+ so which does it work as <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> or the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a>?
