What Does Black Vaginal Blood Clot From Vagina In Pregnancy Indicate?

Posted on Mon, 28 Jul 2014

Question: Dear madam, I had two times of miscarriage happened earlier. After third times pregnancy reading of sonography result, doctor told baby is good and normal. he advised to take one Enoxaparin 40ml and one injection Lonopin -40 for 7 months. however, after taking one Enoxaparin on the date of doctor advice little of black clot blood passed out. Because doctor advice me just one day before, lonopin - 40 injection could not be injected due to non availability. So I have to wait only one day after doctor advice for Lonopin - 40. All these happened with 12 hours of sonography and doctor's advice. Can you kindly suggest me or advice me is that black blood clot is due to miscarriage or for taking enoxaparin40?? Pls infor me immediately.
Regards XXXXXXX

Brief Answer:
It can be a threatened abortion.

Detailed Answer:
Dear XXXXXXX ,

Your doctor has given you these medicines because you had previous abortions.

May i know whether you have been told the exact cause of your abortion like APLA SYNDROME OR SLE etc.

The clot that you passed is from your uterus and is a sign of threatened abortion.

I will advise you to stop all medications immediately and get an urgent sonography now .

Also you need to contact your gynecologist immediately.

Regards,

Dr Som MD

My Gynecologist informed me that black clotted blood isn't result of threatened abortion. if blood is red it will be threatened abortion. he advice me to keep injection if red blood comes out. Well i like to know whats may be the other possibilities of black clotted blood coming out other than abortion.

Dear

Detailed Answer:
if the fresh blood of abortion does not come out immediately its obviously going to clot and turn black after 15 minutes.

Yes abortion is mostly fresh red blood .

But it depends on site of bleed especially if its behind the placenta then it will not come out immediately but just clot and then ooze

Also yes heparin is a drug which increases bleed so that also can be a cause.

Even then it will be called a threatened abortion .

by definition if you are pregnant and if there is blood or black clot coming per vagina its called threatened abortion.

All what i have told can be checked on the net .

These are the 2 cause :

1) spontaneous as you have history of miscarriage

2) heparin
