Hi Kafer, i am not sure about that, i dont have my own horses, but i have been told it is bad to ride while preg due to the jolting etc, personally i would be a little unsure while ttc for those two weeks between ovulating and finding out IYKWIM, maybe while you are in the two week wait i wouldnt ride too much,

On the other hand, it is good excercise and i have heard too that as long as you have been doing something for a while, it is better to keep up with excercise etc that you are used to, maybe ask your gp the next time you see him/her.

I am sure if you take it easy and dont trot or canter too much you should be ok.

I hope i have been of some help!!

Good luck ttc!!!!
