Pregnancy creates lots of hormones and
termination abruptly changes that. Our bodies often react and being irregular
after is not uncommon. If you fear the abortion was not successful, that's a different story. If you had sex unprotected again, then that's another new risk for pregnancy. If either of those are your concerns, then you have to get it checked out. Typically after a surgical abortion, doctors check you again at around 6 weeks to make sure you are healed and all is well.
