We aren't doctors, just other women, and mothers. The test your doctor is suggesting is normal, it's probably an STD panel which tests for several std's including Chlamydia. It's nothing to worry about at all unless you've slept with someone else since the medical termination. As for it taking 3 days and still having pending results, you can always ask how long results take. Im guessing test results can take a week or so though.
I have had the blood test for different STD's and STI's as well as the pelvic exam and all. I had it done when I got married, and about 31/2 years ago.
If you still feel worried,
Feel free to check out the "Ask an Expert" forums which have actual doctors on them.
It doesn't sound like Chlamydia to me . Having lower abdominal pain can be caused by something else . Are you having any other symptoms such as discharge , burning when you urinate , foul odor ? Everyone's body is differnt so everybody may not experience these things if they had Chlamydia . All you can do is wait for your test results . However , It doesn't sound like Chlamydia .
