Does bedrest literally mean to lie down all the time or it’s ok to also just sit down and rest?

Lying down all the time might cause blood clots. U can sit up and rest as well. I just minimise walking when I was bleeding at week 8. I was hospitalised for 3 days and doctor gave me 2 weeks HL to rest at home after. my BB grew by 0.2mm during the 3 days in hospital. Now I'm safely on my 10th week. still taking duphaston prescribed by my kk gynae as he mentioned I still have residual blood from implementation bleeding that might come out. He advised me that I can stop bedrest, can walk but not too much.
