I worked out regularly before getting pregnant (5x per week at a moderate to high intensity, mostly cardio). I got pregnant via <a href="https://glowing.com/glow-fertility-program">IVF</a> and my specialist said to avoid working out and only stick to walking the first trimester. I am in my second trimester now and my regular ob said I have zero restrictions with working out. I worked out Friday for 15 minutes a low-moderate HIIT and had cramping afterwards for a while, no spotting or bleeding. Anyone experience this? I'm now worried to do anything besides walking.
