@babyontiveros, at 8 weeks along, baby is too small to physically cause you any pain. probably just normal first trimester pains from stretching and growing.
Baby's not hurting you Hun. Your body is getting all turned up to begin to get ready for baby. By this time I'm sure you feel lots of pressure in your belly it could be from bloat . Try lots of water and fruits especially so you can be regular my tummy was so bad because I couldn't go to the bathroom
