What comes out when menstruating after tubal ligation?

Normal Menstruation: A tubal ligation affects only your fallopian tube. It does not affect your period and does not affect your hormones. So you continue to build up the inside lining of the uterus and shed it during your period. The lining of the uterus is what comes out. The tubal ligation does not affect this.

No difference: Following a tubal ligation, your uterine lining still responds to your hormones. After ovulation, when you don't conceive, you'll shed your endometrial lining same as before. If it's different in amount or duration, it's probably because you stopped hormonal contraception which also controlled your menstrual cycles. Women always complain of a tl changing their cycles until i remind them of this.
