I don't know what a tubicial is... if it's tubal ligation, your odds are close to none... if it's an ectopic, then you might be able to get pregnant depending on what type of permanent damage was caused...
good luck
If what you had is a tubal ligation, you'll need to have a reversal or do IVF (in-vitro fertilization). Because you're only 38, chances are you could do a reversal but the only way to know is to consult w/a reproductive endocrinologist.
Sorry, I am a bit confused. Are you saying you have gotten pregnant since your tubal? I believe that would mean it didn't work...or perhaps I am missing something. If you had a successful tubal, your chances of conceiving with having a reversal are very slim. I would see your Dr. to discuss, especially if you did get pregnant afterward.
Best of luck to you and take care.
