I'm afraid that there is no other option than abortion. Are you confirm that you are
pregnant. Else i would suggest a laboratory Urine
pregnancy test. There are multiple choice of abortions. DnC at a clinic by trained gyenacologist. MTP by oral medicines.
You can choose whichever method you wish. Also i would like to suggest a vasectomy to avoid such mishaps in future. This operation is completely reversable so no need to worry.
Next Steps
confirmation of pregnancy by urine
pregnancy test. if positive take MTP-KIT by cipla
