Is this normal during pregnancy or am I depressed?

It’s been a hard year. I did lose my job and my husband and I have been under a lot of stress. When we found out I was pregnant, I had an IUD so I was very surprised. My husband is ecstatic and is working harder than ever now. I’m suppose to be doing my part. Looking for a job, keeping up with our apartment while I’m home, making healthy meals so we don’t have to go out for dinner. But I don’t want to do anything. I cannot seem to get myself out of bed. I know I have so much to do! I need to finish the laundry and run some errands. I probably need to take a shower right now and finish wrapping gifts for our Christmas parties this weekend. My husband would probably be disappointed in me for not accomplishing anything all week. I don’t know how to get motivated. I don’t want to do anything right now at all. And that makes me feel horrible because I need to be on my game to prepare for this baby. Only 18 weeks right now. Supposedly when I’m suppose to be feeling my best.
