Hi, I understand that it would be difficult to have another child at this moment. If your confirmation is though urine kit at home, you may want to get USG done also before taking any further steps.
Next Steps
Meet a doctor in person for examination and evaluation, and get the needful done.
Health Tips
Be certain that you want to abort and not continue with the pregnancy. It would be incorrect for anyone to advise medications without having more details about the pregnancy, so meet a doctor in person.
