Not able to have a restful sleep for a few days

Currently I am in my 20 weeks, first time pregnancy. I am usually a light sleeper, easily affected by noise. Moreover, if my husband get really exhausted, he snored quite loud and it further preventing me not able to sleep at night ! The more I tried to sleep the more I hear him snore the more alert I get and cannot sleep . I get really stressed and worried for my health and of course of baby ! How do you all manage ?
