You don't say if you are undergoing assisted reproduction such as IVF, but since this is an IVF/infertility forum I assume that in my response.
I faced a similar dilemma in researching this topic. I'm not medically trained, but in the end what I decided is that the 2 week wait after IVF is a short time (though it feels long), so why do anything that even might work against me? I didn't want to feel that there was anything that I could have done differently if it didn't work. I laid off exercising, stopped drinking any caffeine, and other things as well for the same reason: It's pretty easy to make these small sacrifices for 2 weeks, while IVF is a huge emotional/financial/physical investment. So it was an easy choice for me to hold back on the usual "activities" for a couple of weeks.
However you are trying to get pregnant, good luck and I hope it works out for you!
