IVF and exercise

My husband and I will be starting IVF soon. We are waiting for insurance and then the facility said they will get us scheduled for next available month which appears it will be March or April. I was just wondering if in the mean time it is ok to continue with things such as running? I don’t run fast or anything but just wanted to know if you guys think it’s ok to keep doing in the meantime or would it better to take it easier and do something like walking or yoga? Thanks!!
