So I carried my son completely full term. I mean he came 12 hours before my EDD. But why am I so worried I'm gonna have my baby girl real early this time around. Contractions have begun, I have been under an extreme amount of stress on a daily basis. Work is taking a toll on me but I can't afford to stop yet. And I also have an infection (taking meds to take care of it at the moment) but it also causes my contractions. I struggle to walk because of my hips and back to the point I can't stand up straight. And alone today I have had tons of pelvic pressure and I can feel her wiggling down in my hips almost bringing me to my knees. I'm just worried she will be here sooner than later and I'm not due for 6 more weeks.
