I had a similar experience but my doctor didn't catch the problem before my daughter was born. My daughter had a blockage from her intestine to her tummy. No food, air, gas, etc could go down or come out. She was basically starving to death & no one would listen to me and we almost lost her. Luckily, the ER staff listened to me & got my daughter help-we were flown to UC Davis in Sacramento, CA & my daughter got the surgery needed to correct the issue. She is now 7!!!
Tell your friend to put the stress & fear to God. I know it's hard but she can't do anything at this time & really stressing about it isn't good for her or the baby. She's lucky that they caught it now (if infact the baby does have a blockage). Let her know to find out all she can about the blockage, what treatment needs to be done & when. Knowledge is power!! It will actually give her some relief to know what to expect if it does happen-she won't be in the dark like I was. I wish you all the best, but please emphasize to her to always go with her gut & don't be afraid to ask questions over & over...she knows her body & her baby better than anyone.
Blessing,
