Pregnancy Symptoms in the First Trimester

[healthychick]

Hi there, I was wondering how long people have continued to have period type pains? I'm getting quite regular pains at the moment - i can't remember how long they've been this constant for - at least a week or more (pregnancy brain anyone??) and have come and gone throughout pregnancy. I'm thirteen weeks pregnant tomorrow and though i've read about pains from the uterus stretching in early pregnancy, i can't seem to find much information on it continuing.

I have some lower back pain and a dull ache comes and goes on one side or the other..

any feedback would put my mind at rest.. btw this is my first pregnancy..

cheers :-)
