Hi i am 30 yrs old, and over 2 weeks pregnant but by the pregnancy calculator i am 3 weeks and 3 days, today when stretching i got a sharp pain on my lower left side like under my stomach, hard to explain where only way i can say it is where the top of my leg joins my hip.. and a couple of times today i had small little stiches, i am just wondering is this normal as i am very early and i cant see how i would have any pains.. just a little worried, thank you
