In my opinion, which is not medical, I think you should just listen to your body. Keep your heart rate from getting too high, stay hydrated and keep going for a long as you feel good doing so. I was doing a lot of spin classes when I got my BFP and I kept it up -- until morning sickness kicked my butt harddddd. So I listened to my body and stopped going for a while but I might pick it back up (albeit at a much slower/lower intensity) this week now that I feel a bit more alive.

I"m firmly in the "listen to your body" camp. You'll know pretty quickly if you need to back off! That being said, the first trimester can just be hard for exercise, so if you find yourself too exhausted/nauseous to workout, don't be discouraged! you can always ease back into things in the second trimester when you are feeling better.

I was told to continue everything I was doing before, and listen to my body. Minimize jumping, and start to reduce the amount of ab and core work I was doing before.

I'd just back off the intensity when you're not feeling it. Most likely your perceived intensity will go up, even though your actual intensity will stay the same (or, eventually, decrease).

For my current pregnancy, I got a BFP during marathon training and continued to train and run it (at 16w). But I definitely adjusted a lot of runs/workouts to what I could handle on any given day, made sure to have more food/drink during & after the workouts, and my race plan went out the window -- I was prepared to run the whole thing, walk if I needed to, or even just drop out if anything felt off.

I would just see how you feel doing it. Lower the intensity like others said and see how you feel. If it feels like too much, or it makes you feel nervous, then just see if you can find something else you're more comfortable with.
In my frist pregnancy, I had been doing crossfit for a few months. I was going to keep at it, but it just felt like it was way too much, so I completely stopped it. Now, in my third pregnancy, I feel much more comfortable with my limits so have continued it throughout.

@Mrs. Blush: I exercised intensely from the day I conceived (spin class, long hikes, runs) til the morning I gave birth. It kept me sane!. I kept my HR high too, 140-155 regularly. Baby was fine and I had a wonderful pregnancy.
