I'm currently 21wks+3 and due to complications from very early on in the pregnancy me and DH haven't actually had sex since pretty soon after conception. Three days ago however my Consultant gave me the 'go ahead' that normal relations can resume 
I had always thought that whilst pregnant (I now have an obvious bump which can be a bit tight at times) sex in the Missionary position made the most sense, but now I'm asking is it? I have seen a few threads/posts recently about the risks of pregnant women lying on their backs which kind of defeats the object of missionary?
I just imagine other positions would be uncomfortable? I'm not sure I'd even have the energy to be on top, haha. The thought of my sore boobs and tight bump bouncing up and down doesn't fill me with much excitement, especially when I seem to get so breathless these days with any form of activity 
Any tips??
