mera02 its normal hun i had my first boy at 16 and I experienced the same thing, when u feel stressed try to do something that relaxes you go for a walk or listen to music so that you take your mind off of things for a bit trust me things get easier just stay strong you and your baby will be ok :)..im now 21 expecting baby boy #3 :)
Totally normal. I'm onto pregnancy number 2 with a second boy and I cry over the littlest things. Same with my first.
