If i had a ectopic pregnancy the first time what is my chance of it happening again?

Possible: Did you lose the tube? Any other damage, will guide the possibilities. If uterus and other tube are ok, you can still have satisfactory pregnancy.

10-20% chance: About 1 in every 50 pregnancies is an ectopic pregnancy (2% of all pregnancies). Depending on a variety of factors including age, cause of ectopic, and how the initial ectopic pregnancy was managed, the chance of having another ectopic pregnancy is about 10-20%. Hope this helps and wish you the best going forward.
