It has been one week since I got my BFP, I'm 4w5d. I didn't think it was possible to start having so many pregnancy symptoms so soon. One of my issues has been with sleep, I can not for the life of me get comfortable (I know that's going to get much worse when my belly is the size of a watermelon) and I keep waking up and tossing and turning. I'm not stressed about anything, so could this be hormone changes causing this or could it be completely un related to pregnancy. Has any experianced this this early on in pregnancy???
