Thanks for the query.
Sometimes urine pregnancy
test kits can give false positive results.
If your first beta HCG
test results showed value above 25, then there is possibility of chemical pregnancy.
So along with repeating the test, you once go for ultrasound
to find out the possibility of any retained products.
Sometimes retained products can lead to pain after chemical pregnancy.
If there are no retained products and no signs of infection, you can just go for symptomatic treatment.
