Hello.thanks for trusting the Chat Doctor doctors for your health related queries. I guess your concern is about.chances of getting pregnant even after tubal ligation.my straight forward answer is.YES.there are chances.BUT VERY LESS.chances of getting pregnant after tubal ligation is depends on the method by which tubal ligation was done. Chances of failure of tubal ligation is more with laparoscopic methods then the open method(laparotomy). But u didn't give info regarding this, so It's difficult for me to comment on this. If pregnancy occurs after tubal ligation, then chances of ectopic pregnancy(when pregnancy occurs in another site other than the womb) is high. With the above discussion u can try out my suggestions-1. If u r in doubt then do urinary pregnancy test, tis test kit is available at your medical stores at affordable price, do it ourself, if it negatives then nothing to worry.2. If it is positive then visit to nearby gynecologist.he/she can guide you.3. If everything is normal, then try to take extra precautionary methods during or after sex like use of condom, ejaculation outside the vagina, i-pill use etc. I hope the above information is useful, informative and helpful for u.regards- Chat Doctor.
