Hello and welcome to HCM.
Thank you for your query.
From the information provided, it does sound like the abortion
was successful although, noticing contents of pregnancy
would have provided a further confirmation.
Without visual confirmation of the same, it is protocol to conduct a pregnancy test 24 hours after administration of the tablets (orally or by vagina). So, yes, I would recommend a pregnancy test to confirm the successful nature of the medication.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://doctor.healthcaremagic.com/doctors/dr-shoaib-khan/64581 . I would gladly help you.
