I think it's up to you, really. I rode while I was pregnant. I was actually riding when I felt contractions coming for the first time (advice: don't go far from your barn near the end haha!). I never had any problems riding tho, when I hit 8 months trotting became uncomfortable so I would just walk on the trails then- mostly because riding is calming for me & I was nervous about becoming a mother so it was my peace.
My doctor said it was fine bc I was in good shape & my body was used to to using such muscles from riding everyday.
My mother was super nervous about it however lol.
I've heard jumping isn't good your first trimester but I don't jump so I don't know about that.
However, I did give up working with any green/unbrokes bc that's a risk I ddnt want to take personally. If you have a reliable horse & you feel comfortable doing it with the doctors permission, I say go for it. It is good to stay in shape while pregnant I believe. I never really gave up anything- until maybe my last month when I was just miserable haha.
Whatever you do, good luck & use common sense to stay safe!
