Depression?

💖💙👶🏼

I'm 7.4 weeks pregnant. I have a 5yr old and 3 past miscarriages. My 5 yr old when I was pregnant with her was so easy! Super easy pregnancy. This round, is so hard. I find myself on the couch all day long. I feel so exhausted 24/7. Nauseous, no energy, light headed, heart burn.. everything in the book. Recently I've started almost feeling depressed. Not sure if it's due to me constantly feeling bad. Just like I've lost my happiness towards this pregnancy. One I've wanted so bad! I've never felt this way. Has anyone experienced this?
