Hormonal or depressed?

Hey everyone so I need some advice, I've had previous issues with depression in high school and then again last year when I lost my first baby. I'm currently 26 weeks and 3 days pregnant with my baby boy. Lately I have been constantly thinking I'm not good enough for my boyfriend no matter how much he tells me otherwise, I cry over everything basically, I don't like leaving the house cause I rather just lay in bed and try to sleep but once 11 o'clock rolls around I'm wide awake and cant sleep. I just feel down all the time and don't know how to lift myself back up, it doesn't help that I'm stuck at a job I absolutely hate and we aren't able to move out of our parents house before the baby is born so I also don't feel like anything is going right. I don't know if I should bring it up to my doctor as depression or if I'm just being super hormonal and emotional. At times I feel super down and then when I'm around other people i feel better and like I can actually be happy. I also want to say that I've thought about self harming & smoking weed again but I would never because I don't want to harm my son even a little bit so I don't know if it's worth bringing up
