You might or might not get pregnant after
embryo transfer, but coughing, sneezing
, peeing, pooping, riding in the car over bumps, walking or running will not affect your embryo. It is either going to implant, in which case you could skydive or jump on a trampoline and no affect it, or it is not. The human race would have died out long ago if a woman could lose a baby by walking or sneezing. Take it easy if you like, but don't freak yourself out.
