Honestly hun, parents seem to change their mind a LOT. When I was 18 I moved out on my own since I always seemed to get stuck in the middle of my mom and step dads fights, and me and hubby were supposed to move in together. Well he ended up not moving in then. By the time my lease on my apartment was up, my mom had separated from her husband, and I moved back home. Worst idea EVER. I wasn't even allowed to have my old bedroom back, they had converted mine to an office since its bigger than the other spare rooms. I slept in a guest room, not even on my own bed. I stayed four months, and was gone. Me and DH got a place together, and I never moved back.

Once you move out, parents get used to you being out of the house. Its much different when you come back, especially being pregnant. They might feel like you, your OH, and your baby are now their responsibility, when they were used to none. Try giving them time, and if it gets unbearable do what you guys need to to move. I know how stressed I was, and I cant imagine going through that while I was pregnant. We live very close to my mom and DH's mom now, and it was great while I was pregnant, because I got to spend time with them, then go home. Even now with our daughter, I'm so thankful we have our own home. Good luck sweetie, try to to stress too much, and you shouldn't be working if your pregnancy is high risk. Take care of yourself and LO!
