The question of whether bleeding at 10 weeks of pregnancy will lead to miscarriage has to be analyzed on a case-by-case basis. If there is only a small amount of spotting vaginal bleeding, it usually does not lead to miscarriage because of exertion, emotional excitement, luteal insufficiency or trauma, there may be a small amount of vaginal bleeding. In this case, as long as you treat the symptoms, or rest, and use a little bit of hemostatic, or after symptomatic treatment with these drugs, such as progesterone, which is a birth control drug, there should be no problem and you can continue the pregnancy. However, if you are 10 weeks pregnant and have a lot of vaginal bleeding, or if it lasts for a long time, or if it is accompanied by a lot of bleeding clots, or if you can discharge tissue, it is recommended to go to the hospital in time to have an ultrasound, or to check the progesterone and HCG tests. If the size of the gestational sac is normal and the fetal heartbeat and pressure are present, hospitalization is recommended to keep the fetus alive, which is a safer method. Therefore, whether or not the bleeding will miscarry in the tenth week of pregnancy is determined by the amount of bleeding, it is recommended to go to the hospital in time.
