Pregnancy depression

I didn’t think having depression while pregnant was easy to come across. I thought it could build up from past and being worried but I got pregnancy depression bad. I can’t get to sleep til 7-8 am the next day and won’t get out of bed til 5-6 pm even if I’m awake I just lay there. I always think something is wrong with the baby I fear he/she will have problems from me being depressed. I feel so insecure that I’m not sexually active with my boyfriend, and I be thinking he’s cheating or is going to cheat because of that. He caters to me but I still just got that feeling. I don’t check his phones and he tells me I’m overthinking I probably do but I can’t put it to rest. Have any of you went through this

If so how you dealt with it? Does it ever stop?

UPDATE: we broke up he wanted to mess around and not care about his family. I no longer feel insecure I started doing self love things like getting dressed up and baths. I just want to meet my baby and make his life the best on my part.
