Every morning...

Annelise • 25. Separated. I have a 3year old and 2year old sons.
For the past few days when I wake up I have extreme pressure on my pelvic area. I lay on my left side when I fall asleep an when I wake up it hurts to stretch my legs an roll over. An it all hurts on my pelvic area. I'm 16weeks and 2days. Is it the baby laying low or something else? I just don't know why I'm hurting so much in the morning an don't want to move :/ oh n I thought at first maybe I just need to pee really bad but I'll go to the bathroom an barely pee. Sorry for the tmi. And the pain does go away it's not like it's there all day just in the morning from when my husband goes to work at 6am to about 9am when I finally get out of bed.
