What Does Flesh Like Substance During Periods Indicate?

Dear Doctor,
I am 34 years old female. Wants to plan the third baby after this cycle but before this cycle I took medicine to stop menses (orgametril). I started 4 days before and had 3 tablets daily for 9 days. I got my cycle after 3 days I stopped taking but during menses I felt skin or flesh like object. So doctor shall I plan for the baby after this cycle or wait for few more months. Eagerly waiting for your reply. Thanks
