Weight Loss & pregnancy

All I’ve read is to not diet when pregnant. I’m not currently at a healthy BMI (by about ~15 pounds). If I’m losing at a safe rate of 2 lbs a week is that still ok to do? What’s worse? Being over weight while pregnant or cutting back while pregnant? We are actively trying so I’m trying to be prepared for what to do when I end up with a positive if it’s soon.
