yes you can be pregnant and not know it until the second trimester. if so you are one lucky woman to not have morning sickness or other side effects that can occur (and do for the majority) within the first 3 months. if you feel movement i would definitely say take an ept or better yet just go to your gynecologist. the body kinda gets used to pregnancy the second time around and baby movement does occur earlier than with the first child. especially since "mom" has experience and knows the feeling. also by the end of the fourth month the pouch shows much more than it did with a first child. some women don't show much with the first child until 7 months! and even then for some it's just a little pop!
can you be in your second trimester of pregnancy and not know you were pregnant. i feel movement like i did with my first i have all the symptoms i need to know if its possible
