Thanks for writing to us with your health concern.
Small RPOC of 8 mm does not mandate a repeat D and C.
If the RPOC measure more than 15 mm, only then they are of concern.
Small RPOC often respond to antibiotics or repeat dosage of Misoprostol
However, they could be responsible ofr your cramps and pressure sensation.
The first period after a D and C can occur anytime between 4 - 6 weeks after the procedure.
You should not be sexually active for a month following a D and C
This gives time to your tissues to heal.
The amount of discomfort you describe is not normal.
The RPOC could have persisted.
Persistent RPOC can lead to infection.
Without consulting a gynaecologist it is difficult to get a specific diagnosis.
A pelvic ultrasound
scan is confirmatory and a vaginal swab will pinpoint infection.
All the best
Please feel free to discuss further.
