Hello,
Thanks for posting your query at DoctorSpring.com
For a few weeks after a D and E, it is normal to have abnormal bleeding and spotting.
What is most important is that you should have had a follow up ultrasound scan to confirm that the uterus is empty and the procedure was complete.
If that is done, do not worry.
Give yourself upto 2 - 3 months for your cycles to regulate , and meanwhile have protected sex.
All the best
Please feel free to discuss further.
Regards.
