I could really use some advice from anyone has ever been in this situation or something similar. Baby 1: we STRUGGLED to get pregnant, 3 rounds of IVF and we finally had our miracle baby. Baby number two: all those IVF meds jump started my body and when my first baby was 7 months old I unintentionally got pregnant, we were so happy!!! Never thought we could conceive naturally. So the age gap between my kids is 16 months. Now for my dilemma: my Dad and best friend died a few months ago and I have been DEVASTATED. I was so stressed and even on the strongest birth control they could put me on I was having periods every two weeks or three weeks sometimes so I decided to get off birth control for a few months. We did NOT want another baby but now I am pregnant. I am almost 36 years old and we never had the intention of having another. What’s even crazier is the baby‘s due date is the1 year anniversary of my dad‘s death. I am TORN because I know how hard it is to struggle with getting pregnant but we didn’t plan for this. We would have to get new cars, would have to add on another room to our house for new baby’s room, 3 college tuitions, 3 cars etc. I feel like it’s a sign we are meant to have the baby given the due date but again we didn’t want another one. This would be my 3rd c section and had issues with the previous ones. Our kids are so close in age it’s like raising twins and my daughter already struggles with fighting for attention I’m worried how this will affect her. Should we have this baby is the question. It would really affect our lives and my other kids.
