I was six months pregnant when I was involved in a vehicle accident. Exactly one month later I went into preterm labor and had to be put on bedrest. Three weeks later I had to have surgery for a torsed ovary that had ruptured and was 11 cm. My baby had to be delivered three days later due to high blood pressure 6 weeks premature. Could the vehicle accident have caused my torsed ovary? I have read that it is very rare for an ovary torsion to occur in the third trimester and for it to turn on itself twice.
