Staining from uterine blood clot

20 May, 2014


I am 11 weeks pregnant and had some brown staining today on colored underwear.

I went to the doctor to find out why I was bleeding (because I was concerned about the pregnancy) and he found a blood clot in my uterus which likely contributed to the blood that I saw.

Since the blood was likely from the uterus, but from a blood clot (makkah?) am I in niddah?



B'Sha'ah tovah!

Bleeding that is caused by a blood clot in the uterus would render a woman niddah. In general, since there is always a chance that bleeding that comes from a wound in the uterus is accompanied by regular uterine bleeding, we can not attribute uterine bleeding to dam makkah unless there is a known cause of trauma to the uterus.

However, since you only experienced staining on colored underwear, and not an actual flow, the stains may be disregarded and you were not rendered niddah.

You should continue taking precautions against becoming niddah from any further staining by wearing colored underwear and waiting 15 seconds after urinating before wiping. See our article on stains for more details.

We wish you a smooth and healthy pregnancy!
