when i first went to the doctor they went by my last period and then i had an ultrasound and said i wasnt as far along as they thought. right now they say im 28weeks but according to my period im 31. and i was almost positive about the day i concieved. could the ultrasound be wrong? they just go by weight and height, and my daughter was a small baby so mabe he is too and it just looks like im not as far? also i have been having contractions, and that would make more sense if i was further along.
