So I know Im not the only one that suffers from cold sores but since I have gotten older the frequency has changed. I have PCOS and have had issues since I was a teenager but the first cold sore I ever had came with my first miscarriage. Then I used to get them when I was really sick and with my other miscarriages. Now that I am 30 I have started to get them the week before my period but only some months?! There is no rhyme or reason some months I will get one or two and some months I get none?! HELP!!! What does this mean? Anyone else experiencing this?
