Just wondering, I know that during ovulation your immune system is weaker, but has anyone found that having endo also makes your immune system....crap!! I have the mirena coil and until recently hadn't had a period. I'm constantly getting flu, colds and viruses. I'm known as the 'sicky person' amongst friends and colleagues. I'm wondering if their is any connection between my Endo and my inability to fight off germs and bugs!!
