months to weeks Ratio

Jessica • My husband and I are expecting our first child in December. This app has been a great help.
I wish glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> would tell me how many months pregnant I am not just weeks. People ask me and I don't know what to tell them. I got this picture from a foram online is it right?
