bad day!!!!

so yesterday my SO woke up in a bad mood we all have our days!! I didn't sleep well an apparently neither did he well I'm a SAHM an I usually do all household stuff during the week and he does it on the weekend but we had a hectic busy weekend so nothing got done and I mean nothing. our 2 yo decided to be a handful and we have 3 boys i am almost 28w with are girl I have cerebral palsy and I'm not use to carrying a girl... she lays on my pelvic bone an makes it hard for me to walk. my SO noticed I wasn't in a good mood and apologized for his actions an mood an came home and got down on his knees as I was seating in the chair an hugged me. anyone else just have an emotional bad day at this stage of pregnancy?.... I am very blessed to have my SO but the last thing he said was I forget your pregnant.. and I'm like forget I'm pregnant umm how... that just makes me worry I've been a single mom before an I don't want to do it again but with that comment I'm afraid things will change after the baby an maybe he'll leave. sorry for the long post I just needed to vent an some advice or reassurance do y'all think it's just my hormones am I seeing to much into this?
