I am 12 weeks pregnant and due to go for my 12 week scan next week but i have just been told that i have no immunity to rubella and should stay away from anyone with rubella symptoms (50% of cases have no symptoms though, so this is very hard to do!) and i am concerned that attending the hospital will expose me to unnecessary risk . I work from home and so have not had much exposure to the general public/young children so far. I also had a scan at 11 weeks due to a small bleed and thank fully everything was ok at this stage. I am considering cancelling the scan but still going for the 20 week scan as the risk is much lower at this point. I would be grateful for any opinions as i am so worried.
