Thanks for your question on Health Care Magic.
I can understand your situation and problem.
First of all, no need to worry for
cervical cancer because your all reports are negative for cancer.
You are having
chlamydia infection due to IUD in
uterus.
IUD weakens local uterine defense system, so women on IUD are more prone to
STD s.
You are mostly infected through your husband.
Male
urethra is very protective against infection. So your husband might be carrying chlamydia without infecting him.
And during sexual Intercourse, you are infected.
Since your defense system is weak due to IUD, you are having symptoms of infection.
So better to get done sensitivity report for guidance of effective antibiotic therapy.
No need to worry for cervical cancer.
Hope I have solved your query.
Wish you good health. Thanks.
