I haven't been on bedrest, but I have read about it. It can last up to the birth of the child, depending on why you were put on bedrest. Bedrest can also last as long as your problem persisits. Once it has gone, or gotten much better, you will be taken off bedrest and back on restrictions.
I hope you are better and don't have to resort to bedrest.
i was put on bed rest and no sexual activity for a week a few weeks ago i have been having spotting since i was 8weeks i am now 15 weeks i had my ultrasound done and she said that part of my placenta was over my cervix that is why she said no sex and when im on my feet at work more than about 5hrs i start spotting again so i went on bed rest for 7 days and went back to work but im only working 4-5 hrs a day 3 days a week and so far things are ok, i have another ultrasound done sept 2 so i guess that will tell us more.
