Depression?

I'm currently 36 weeks, but tbh this whole pregnancy has been hard emotionally. I feel like my relatives with my husband had gone downhill, we have good days but there's no connection sexually which makes me feel so ugly fat and horrible about myself. Probably the last two months have been the worse. I think I cry myself to sleep almost every night. Idk if it's just hormones or what but him not being attracted to me hurts. I'm super scared of being depressed and not knowing of of being depressed after birth especially since I have a one year old. Any suggestions tips??
