Hi, I had gone through your question and understand your concerns. Provera 10 g is a progestiron harmone which can be used in different conditions... According to your dates gestational age will be 8- 10 weeks.. It will be caluculated like this : From your last period date till today may9-july1=7 weeks+2 weeks from the ovulation , so it will be around 8-9 weeks. so,only provera 10 mg wiil not be effective. Your baby age is more than 8 weeks ,so it is better to consult a gynecologist ,one more thing is IF YOU USE IT provera works but there is a chance of incomplete abortion and may lead to complications. Get an ultrasound and get the exact gestational age and get appropriate medicine for abortion If you have already used the tablet ,even then get an ultrasound to rule out any reminent, which may get infected leads to complications in the future. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. thank you.
