Stressed

So I feel as if im in a real bind right now and so stressed , and maybe i shouldnt be so stressed but I cant help it.. So i work at walmart and ive been there almost a year and a half but im only part time ... and they dont offer paid martineity leave for part time, what are ways i can get money while on leave i still have ab 15 weeks before the baby is due but i dont wanna wait til the last min to figure it out ... esp with gonna have a new born and bills... i got everything i need for her expect a few things but will be prepared withing a month or so ... what should i do ab being able to pay my bills and be able to afford stuff a newborn needs since they dont offer paid martineity leave ..
