Defying million-to-one odds and everything you ever knew about fertility and hormones and monthly cycles, a 29-year-old mother of two got pregnant a couple of times within the span of a few weeks.

After she initially became pregnant, her menstrual cycle soldiered on none-the-wiser and released an egg the following month, which also became fertilized and eventually implanted. Oh, and Mom was on the pill the whole time.

The mother found out she was pregnant with two non-twins at a routine 12-week ultrasound. While checking over the older fetus – flailing arms and legs and all – the techs also saw a blob, which appeared to be more like a fetus nine weeks along. And it, too, was alive. A subsequent ultrasound showed that the younger fetus was still hanging in there and developing according to schedule -- three weeks after the first one.

Mom continued to grow along with the fetuses, which, while housed in the same uterus at the same time, were technically not twins, but still must suffer the fate of all sisters close in age -- identical outfits.

The girls were born at 29 and 34 weeks gestation after an emergency c-section but are now home, thriving and happy.

Armchair Family Planning Counselor here suggests this mother find an alternative method for birth control. This woman got pregnant not only while she was on the pill, not only while she was already pregnant, but while she was already pregnant and still taking the pill. Her ovaries are firing off rounds of eggs like automatic weapons.
