39 years ago I gave birth to a boy and then to a "surprise" girl. My doctor was basically shocked as he had never heard 2 heart beats and my total wgt gain was only 23 lbs. He estimated that they were up to 4 wks apart in conception! I would love to be in touch with someone else who experienced this "wonder" Mystery!!!!!!

I am actually the oldest of a set of Superfetation twins. My younger twin sister is two weeks younger then myself. When we were born we were delivered naturally, but with out knowing I actually saved my sisters life. She came out breach and could have died if I was not born first. The doctors noticed the entire way through my mothers pregnancy that the babies [myself and my twin sister] were developing at a rate approximately two weeks apart. I was born full term, my sister two weeks prem. She has not developed any health issues except that she never developed any enamel on some of her adult teeth due to her premature delivery. I weighed 6 pounds four ounces, my sister was only 4 pounds six ounces. So if anyone would like to get in touch with me reply to this message and then we can get in contact by Email.
