Exercise after successful IVF

Da
Have any of you fit ladies come out the other side of <a href="https://glowing.com/glow-fertility-program">IVF</a>? 
I'm going mad not being able to really workout but after three <a href="https://glowing.com/glow-fertility-program">IVF</a> cycles I'm now 5 weeks pregnant. I'm still petrified of making my body temp rise and compromising this super special little baby. 
Any experience with this that you can share with me?
