Finding contradicting info on this. Base on the following I'm still confused.

"The guide says you are not covered for "Travel arrangements that are scheduled to take place after the twenty-sixth (26th) week of pregnancy; or when any multiple pregnancy, with or without complications, occurs prior to the initial deposit date or booking date of the Trip"

My wife and I booked a flight for a Family reunion for next July 19th 2020. We booked this flight on 11/26/2019. On the 3rd week of December we find out that we are pregnant. We had our 1st doc appointment this past Friday that put our measurements at 8 weeks 6 days pregnant with a delivery date of August 8th. Due to this the whole family is rescheduling the reunion to June 7th. What's the best way to go about this, cancel the flight and file a claim, or pay a change flight fee and hope to get reimburse? Is this scenario covered since we booked the flight before we knew we were pregnant? Airline is American Airlines. Card used is Chase sapphire reserve. Paid partially with reward points thru the chase travel portal. Thanks
