I imagine the doctors where correct, often blood pressure goes up with pregnancy, so that may effect the umbrella, and cause it to collapse.
Some one should remind her that her health is golden gift, you can;t go back and say i want to do it all over again.
If u notice her lips are blue, get her silly butt to the ER.
She needs a wake up call.. i would give anything to be healthy and go to the bar, she is making things worse..hell i never heard of alcohol helping anything.
your a good friend, watch her back good luck ww
