Clinics will normally brush women off after a procedure, and are known for minimizing post-procedure problems. If you feel like 'something is wrong', trust your instincts and go to a doctor. It's better to be safe than sorry, with medical issues. If YOU are alarmed and she's not even concerned, that's a bad sign. Far better to get a professional to check her out.
Most abortions are safe and uncomplicated, and most women have no problems physically afterwards.
Don't worry about being embarrassed or ashamed about calling and telling what is going on with you, or that you've had an abortion. They won't mind, that's what triage nurses are for, to judge whether a problem needs immediate medical care or not. Depending on how far along in the pregnancy you were, and how sensitive you are to hormones, you may have pregnancy hormones still in your body for up to a year after an abortion. For the first 2-4 weeks following the abortion, your hormones will make you feel like you are on an emotional rollercoaster ride. It can take from 6-24 months after an interrupted pregnancy before your body and hormonal systems feel completely 'back to normal' again.
