Thanks for the query.
You can go for medical termination of pregnancy
as you are 8 weeks pregnant.
Consult your doctor and with her advice take tablets to induce the blood flow.
Mostly all the products of gestation will come out with tablets. If an products remain you may need D&C.
Usually miscarriages in first trimester will occur due to congenital anomalies, chromosomal defects, hormonal
Usually the will not repeat in the next pregnancies. So you may not have problem in conceiving but better to get investigated thoroughly.
