I am 13 weeks pregnant and have been spotting. I was diagnosed with something called subchorionic bleeding and was told that the blood is coming from the maternal side of the placenta. Can you please tell me if that renders me in niddah?
We're sorry to hear of the complications you are facing and wish you a smooth pregnancy from now on.
In general, bleeding from the placenta is considered dam koshi, which makes you niddah, and not dam makkah, (bleeding from an injury, which does not). You are considered a niddah and must immerse in the mikveh.
The process of becoming tehorah is the same during pregnancy as at other times. However, in your case, the bedikot can be done less deeply so they do not touch the cervix. You should gently insert the cloth until the first knuckle, concentrating more on going around carefully and less on going deeply. If you have difficulty getting clean bedikot, please ask a halachic question about reducing the number of bedikot.
