Being pregnant, juggling all the other daily activities you do, having a relationship, friends, family, maybe work, etc. All can get very stressful especially as you are pregnant and your hormones are changing, you are gaining weight etc. Discuss with your dr, as there are counselors to help and support groups if need be. Do not get overwhelmed as this is common and you will get through it.
