It's normal lalo pag nasa 1st trimester ka palang, but everything will be back naman normally when you reach your 2nd trimester onwards. Di naman sya mkaka effect kay Baby, kasi its part of your pregnancy naman.
normal yan. happened to me b4 ko pa malaman na buntis ako. i cry w/o any reason
wala naman wag lang madalas if you feel down think of happy thoughts.
