...Vanishing Twin....

I'm so sad...this is the third time this has happened......another baby I won't know, another sibling my children won't know, a child left without his/her twin.....I cried..,and to top it all off I have to monitored for reabsorption. The last time this happened, the sac popped and it was scary. I went to the hospital and thank God my middle child survived but the twin was gone...this just depresses me so much...
