Is this ppd?

Im nearly 14 weeks pp and this past month, month and a half ive just felt so low. Im constantly irritated and angry and have become resentful towards my partner. He doesnt help much because he works and believes the weekends should be his free time so i do everything on my own. I feel like i have no one except my baby girl, none of my friends have bothered with me since becoming pregnant and my partner is going out drinking 3 or 4 times a week because he cant stand my moods. I feel alone and constantly on the verge of tears because i just feel trapped. Im worried about mentioning how i feel to a doctor because i have a history of self harm and im terrified incase they think my baby would be at risk some way. Does this sound like ppd and if so, would a doctor use my past against me in some way? I love my baby so much and feel awful for feeling so low during her first months of life
