Dull pain in right ovary, tenderness, 4 weeks after surgical termination. Need some input please.

%-) I had a surgical termination about 4 weeks ago. I was nearly 9 weeks along. I noticed prior to the surgery that my left ovary was sore and tender to the touch. Everything went smoothly with my surgery and the recovery seemed to go as expected. I took all my antibiotics and have had no noticeable signs of infection. The clinic I went to was extremely expensive and informed me that they would charge extra for a followup appointment. I am short on funds right now so I opted not to schedule a followup appointment. Now, it is nearly four weeks after my surgery and I just began experiencing a dull and aching pain in my right ovary yesterday. I figured it would go away but today it is now tender to the touch. I still have a slight pink/brown discharge every once in a while. But no bleeding for a couple weeks now. I have no signs of an infection. No abnormal smell, fever, etc. I am just wondering if this new pain is normal.:S I do not wish to bother the clinic for something that seems minor but this symptom is similar to what I felt when I was pregnant before the abortion....only on the left side. I have not been sexually active without the use of a condom and contraceptive gel. I was hoping someone might be able to provide some insight please.
