Boobs got bigger/hormones/skin/fat redistribution (pregnant, arms, breasts)

[aek11]

so its a multifaceted question.

1. ive had major nose blackheads since i went through puberty. ive also always had slightly long menstruation cycles averaging 32 days per cycle. and occasional pimples during that time of the month. then a few months ago, im not exactly why but my periods became about 26 to 28 days. all my blackheads were gone. i had the best skin ive ever had and zero pimples.
2. also, my fat distribution changed. i used to gain weight most and first on face, tummy, butt, legs. yet no matter how much i gained weight, my boobs never got big and my arms were always skinny. but something changed and now all of a sudden, i lost all my face and leg snd tummy fat but my arms are huge. and my boobs got bigger.

THEN I GOT PREGNANT but it didnt stick. but after that my blackheads came back. my skin which used to be really smooth became bumpy. i started getting the occasional pimple before. the fat distribution got more extreme and my face lost all its fat and my boobs got way bigger.

so my theory is that my skin and blackheads must be really affected by my hormones. because there seems to be a correlation between length of cycles and skin.
but besides that..i dont know what i did for my hormones to have changed as thid happened before the pregnancy.
also. is it possible for breasts to get noticeably larger if one was to get pregnant...even if theyre not pregnant anymore?

what factors could have changed my hormones?

is fat distribution change a common thing as you get older? im 25 by the way and all this happenrd
