Thanks for the query.
After removal of IUCD it will take some time for regularization of the hormonal
That may be responsible for your spotting.
Possibly this will subside soon.
If the spotting persists, once consult gynecologist and take tablets to control the spotting.
If you had unprotected intercourse
after removal of the IUCD, there is possibility of pregnancy
In that case check for pregnancy once.
If the test comes positive, consult gynecologist get examined to rule out the possibility of miscarriage
If the test comes negative, no need to worry.
If your doctor recommends you can use hormonal pills for few months to regularize the cycles.
