Use of Lantus and Humalog during pregnancy

Hi everyone! I have Type 1 diabetes and I use Lantus an Humalog for my treatment. I am wondering if these insulins can be used during pregnancy as well or if research indicates that t would be safer for my baby to treat myself with another type of insulin. I am not pregnant yet, I am starting to do some research about pregnancy and type 1 diabetes. Thanks to all for any information you might have available on this matter!
