After meeting with our NFP teacher we still don't know really when this surprise child was conceived. Logically it doesn't make sense. Hence we can't figure out a due date. It could be as early as March 29th or as late as April 13th. So for now I just picked April 10th and went with that. Which puts me at almost 5 weeks. Not sure if I will ask for a dating u/s or not. We will def have one around 18-20 weeks to determine the baby's sex and to check the baby's heart for any issues.
At this point I am going to interview the midwife that took over the midwife's office in Concord ( where I went for the later half of my pre natals when pregnant with Israel) and take it from there.
