Is this a form of ppd

So i always wanted a baby. And because of a lot of health issues i wasn’t sure if I’d have one . Then i got pregnant but had a miscarriage and it broke me . Then i got pregnant again and 3 months ago had a perfect healthy baby girl . She’s literally the dream baby, she’s adorable , a mommas girl but looks like daddy, sleeps through the night , doesn’t cry , etc . Well people keep asking me if i want another one and i really don’t . Like i use condoms when me and my husband have sex and he also pulls out because i don’t want any chances . I cry when people talk about me having another one because i can’t imagine another baby the way i love my daughter or having to split my attention away from her and into two . Before i had heard i wanted 2 kids now i get depressed thinking about it . Is this normal ? It’s crazy because my sister had 4 kids and of course i love them all and i love kids , i have siblings as well and we’re all close but it’s just like ok it worked out good for them but i only need my daughter which my husband doesn’t like because he wants atleast one more and doesn’t want our daughter to be lonely. Is this normal ? Or is it apart of ppd
