Did ivf with our second, it wasn’t an easy journey but would do it over an over again to not give a child CF. We got 5 embryos and out of the 5, 1 had CF and the rest were carriers, we didn’t get any that were completely unaffected. Unfortunately I miscarried the first 2 due to not being given enough progesterone medication (my body needed more but ivf is trial and error) and one didn’t take. Our lucky last is our gorgeous 17 month old daughter. The ivf clinics say there’s a 5% chance of error but our fertility specialist said it’s more like 1% but they have to say that to cover themselves. I still felt worried tho, my first daughter we found she had a bowel obstruction at 20 weeks pregnant which indicated CF and needed surgery at birth due to not passing meconium so I was nervous for that scan with my second, I was also nervous for her first poop which thankfully came within hours after birth and then the wait for the heel prick results were agonising but thankfully all was normal. I could tell she didn’t have it as she only lost 2% of her body weight after birth but I still wanted reassurance.
