Drug: Levonorgestrel IUS (Mirena, BAY86-5028)
LNG-IUS once inserted will be effective for 5 years.
Other Name: Mirena Group

Group 2
Copper IUDs with different shape and with or without drugs
Device: Copper-IUD
Copper-IUD once inserted will be effective for more than 10 years.

Primary Outcome Measures :
  1. The number of bleeding/spotting days assessed over the second 90-day reference period after induced abortion [ Time Frame: Months 4 to 6 ]
    The 90-day reference period is recommended by the WHO. Day 1 is defined as the insertion day.

Secondary Outcome Measures :
  1. Menstrual bleeding intensity [ Time Frame: up to 6 months ]

    It will be captured by patient dairy and measured by subjective scale as below.

    • No bleeding
    • Light bleeding
    • Normal bleeding
    • Heavy bleeding
    • Very heavy bleeding

  2. Abortion related bleeding days [ Time Frame: up to 1 month ]
  3. Time to the first menstrual bleeding following abortion [ Time Frame: up to 2 months ]
    This data will be calculated by days

  4. Participants continuation rates of Mirena and Cu-IUD [ Time Frame: up to 6 months ]
  5. Reasons for discontinuation of Mirena and Cu-IUD [ Time Frame: Up to 6 months ]
    It will be calculated by percentage

  6. Participants satisfaction rates of Mirena and Cu-IUD [ Time Frame: Up to 6 months ]

    It will be captured by satisfaction scale as below.

    • Very satisfied
    • Rather satisfied
    • neither satisfied nor dissatisfied
    • Rather unsatisfied
    • Very unsatisfied

  7. Percentage of participants with adverse events [ Time Frame: Up to 6 months ]
    Adverse events included: Pelvic inflammatory disease, Expulsion and Others.)
