horseback riding while pregnant?

Any horse lovers out there?

I am a Junior in College, I decided to change my major to Equine. I love horses. After I started the papers to change schools I got a BFP, so Im about 4 weeks now. Today I saw my counselor. She does know I am pregnant. We altered my schedule so I am not taking any of the dangerous classes, like the one where they teach you to ride.

There is one class I question. It involves working with young colts. I think its teaching them to be handeled and wear a bridle and stuff. My counselor thinks this should be fine for me, since the horses will be my size.

this is my third pregnancy, hopefully second baby, so Im no fool to whats going to happen to my body. But I havent spent any time with colts. Should I be worried about one kicking me? I can wait to take the class, but really would like to take it if it is safe.

Also, the classes I cant take we are going to schedule for the spring after ive had baby. but, im due around christmas and classes start up around mid january. can i really ride a horse that soon? will it hurt my crotch sitting on a saddle? or will i probably be ok? with my first child, i only had superficial tears, and hope for this to be the same.

thanks for answering if you know anything about colts.
