Low placenta

Patient: Hello. I have been told I have a low placenta that reaches/covers the internal os at my 20 week scan. The scanner gave me no information really and I’m worried I will bleed. I know that often they move up and they are checking again at 32 weeks. I read that you should take it very easy but I work and have a toddler to look after so this is almost impossible! Please could you give me a little more info on this? Many thanks.

Symptoms: No bleeding yet.
