I'm wondering if anything we do in the two week wait can affect or compromise implantation/future pregnancy? If we have regular sex or exercise, or even sneeze in the two week wait, is it possible that the egg could be "thrown off course" so to say? I know it sounds silly but something so tiny is attaching itself I wonder if any physical activities we do could affect our chances of implantation, therefore preventing a future pregnancy without realising. For example if we are 5+ days past ovulation and we do alot of strenous exercise, or have regular sex, can any of this even have a slight chance of preventing an egg/sperm from implantation? I hope that doesnt sound silly, i have so many scenarios run through my head when i think of whats happening down there I wonder if even the slightest things could have an affect. What do you think?
