Hi-I wonder if any MN out here know definitively whether your immunity is naturally lowered during pregancy? Up until a few years ago , I rarely got a cold. This year so far during my mid trimester I picked up a terrible cold that has lasted on/off about 6 weeks , or, I got one in mid January, sort of got over it and have now contracted another stonker. Either way my immune system is not battling it very well, and it's getting me down, especially when having to deal with all the other minor aliments of pregancy. I also happen to be over 40 , so the ageing process might have something to do with it!
