12 weeks pregnant & my Dr recommended 2 weeks of bed rest. I have a low placenta, bleeding (when I wipe after using the bathroom). However I am a nursing student and can not stay on my bed rest.

Last year I had a incomplete miscarriage (D&C surgery) around 10 weeks. My hormones were not balanced progesterone & estrogen level was low. My placenta was also low. I also had 2 c- section (4 years & 7 years ago).
What should I do? I am scared that might have another miscarriage.
