Karin,
my cousin's gf got preggo right after chemo for breast cancer (which they told her she would not be able to for yrs) at 21. She ended up pregoo with twins (my aunts are twins

) anyhoo 4-5 months into the pregnancy they realized one of the babies died and if they did not do surgery then the other would to. The surgery was risky though too. Well she opted to have the surgery at I think 20 weeks and they removed 1 baby and the other stayed in. Meena is now 5 yrs old and a very healthy lil girl!
Did u have an u/s before this happened? I can't remember

I was told I had a vanishing twin cause when I gave birth there were 2 amniotic sacs. But I had u/s done at 5,9,13,19,32 weeks (i was high risk) and they always saw only 1 so they say it must have been wayyy early on.
How u feeling though?? Going stir crazy yet???
