As a rule I try not to take a lot of medication anyway. I have been taking OPKs and I am right at ovulation. And of course I woke up feeling sick. I am sure it's just a cold but I can't make up my mind if I should take some medicine which will make me feel better and in turn more in the mood, or if taking medicine will interfere with ovulation or implantation. Probably really over thinking this but I hate to "waste" a month.
