It takes sometime for the serum and urine hCG
levels to come down after an abortion
. Therefore, the pregnancy
test remains positive for sometime after an abortion, even up to 4-6 weeks. Since you had a sonogram, I think your doctor must have ruled out any possibility of ectopic pregnancy. Lifting heavy weights often gives rise to muscular spasms irrespective of pregnancy. Anyway, you have an appointment with your doctor today, so please take further advice from your doctor. Good luck.
