Postpartum Blues

Hi everyone . I am a new mother to my first baby who is now 14 days old . Started from the 4th day after delivery, I came home for my confinement and I have been feeling teary and sad up until today. My confinement lady is taking care my newborn most of the day, but i don’t know why I’m feeling like this . I feel like my life will change drastically , what have I done , why am I thinking like this I feel so guilty I feel like a bad mom. I have gone through multiple failed IUI and IVFS and miscarriage for in 6 years of my infertility journey, and I had my miracle baby in my arms now but why am I feeling like this :( I just want to get better I just want to be happy again. The day is hard especially when the sun is going down. My husband is very supportive though. My feelings come and go . They only last for a few minutes up to an hour then I’m ok. Any of you experience this , how long did it get better ? I really hope to get better and not have this minded and be a good wife and mother to my baby . Thank you .
