Possible PPD... Kinda long

So this is my third child I had her earlier this month (almost 2 weeks now). A lot has gone on and I feel so stressed out about everything... I have a 4 year old and 2 year old first of all so that is bad enough. I am 23 work my ass off for everything I have and had to move back in with my parents because I didn't have rent money for October... Then on top of all that my younger brother got in trouble with the law and facing a felony charge which I am devastated about because he is a good kid just he was being stupid and honestly wrong place at the wrong time... My fiancee did just get his cdl and has now a wonderful job and he has helped out with all 3 of our children. Just I am not crying all the time or mad I just have an overwhelming anxiety but I mean all of those together with the fact that I also have a past with PPD too doesn't help. I Feel like it could be to early though to call the doctor and talk to them about meds then I am pumping and if it would mess with my supply. I don't know maybe it isn't ppd and it is seriously because I am stressed out. I am just trying to figure out what to do. I am confused about the whole thing because if it Is ppd I had it so much differently the last 2 times it would be no where near the same.
