Can any of the following prevent implantation of the embryo; driving on bumpy roads, eating of spicy foods, wearing of tight clothings around the waist etc. thank you.?

No: It is a natural process that occurs soon after sex.

Nope: If any of the above were true, i know of a whole generation of truck-driving, bike riding, latina women who would have never had children... Don't buy into everything you hear, or what i call "flea-market medicine." take care & go ahead wear your tight jeans, go 4-wheelin', & chase it down with some jalapeño poppers!

No, no, no, and no: Rides make no difference, nor does food nor clothing. If it's going to happen, it'll happen.
