Um, it sounds like ParisMaman is talking about ovulation time, not PMS.
Before I was TTC, I noticed several times that I O'd a couple of days into an illness, like flu or strep. I thought it was strange because I have very irregular (infrequent) cycles, and I'm always hearing how stress is bad for cycles, so why would I finally O just when my body is under stress?
Now I'm wondering, could the effect be the other way around? Is it because I was about to O that my immune system let down its guard a little bit so I got sick?
I know that it's important not to have the immune system be overactive when the zygote is trying to implant because your body needs to be able to accept a genetically distinct organism attaching to the blood supply...so maybe the immune system purposely relaxes for that reason? Hmmm....
While TTC, I haven't gotten sick at all
but have noticed a definite increase in feelings of emotional vulnerability around the time of O, which my partner is inclined to consider a form of mental illness.
: It's cruelly ironic that we are more likely to get into fights and I am more likely to burst into tears, either of which makes us less likely to have sex, just when we most need to do it!
