I used to think that I'd be safe working around/riding horses whilst pregnant. I've got qualifications and I used to work as a riding instructor, it was all I did for a long time.
I remember posting when I first got pregnant with Beau wether or not it would be safe to continue. People advised me it'd be best to give up but I thought I knew better. Beau died from a little fall I had whilst on the yard. I never knew such a small impact on my stomach could have caused such a fatal thing to happen. Needless to say I haven't been near a horse since and I never plan on getting near one again. It's sad because horses were my life, the only thing I could do and it's gone. When I go back to work I'll have to start at the bottom of the ladder in another career just because I made a misjudgment.
It's totally up to the individual what you do but in my opinion now..... I'd rather give up something I love for a few months, than lose it for a life time.
Good luck whatever you decide hun
