For certain, no
Agree with both doctors who posted previously; i just want to weigh in as well.
Totally normal uteri can be flexed, tilted, and even rotated: all are variations of normal. Some are more common than others. The retro-flexed or retro-verted uterus
('back tilted') is about 10% of women but it' s normal. It won't cause ectopic anymore than it causes crab grass to grow in your lawn :).
