Spice things up

Recently my husband and I have been going through a rough patch/ hard times. Our relationship has basically been put on stand by since having our son 10 months ago and then recently found out I’m 17 weeks pregnant. I’m looking for ways to spice up our intimacy. Whether it’s things in the bedroom, texting, etc.. I just need some help. I feel ugly and fat from being pregnant back to back and I’m just not comfortable in my skin. Any advice, or encouraging words are welcomed!
