Hallow Dear, With the history of repeated previous miscarriages, you have to keep possibility of miscarriage in consideration. You had nausea and vomiting along with a missed period. So the possibility of pregnancy is very high. In fact you could have gone for some pregnancy test earlier; particularly because you have a bad obstetric history. However, now you can submit yourself for ultrasonography. If you are aborting and the bleeding has not stooped, ultrasonography will clearly give you the evidence. If the pregnancy is disturbed and non-viable, you will require evacuation of uterus. However, if the pregnancy is still intact and not separated from the uterine wall, you stand a good chance to continuation of pregnancy. Your pregnancy test also then would be positive. In that case, please report to your Gynaecologist. Take complete bed rest. You may require some Progestational preparation like Susten or hCG injection to support and stabilize the pregnancy. I hope this provides you preliminary guidelines. Dr. Nishikant Shrotri
