I always have that

@lovelycin09,

This was the only time, they said it could of been from the way the baby moved ( the dr told me she VERY active for 21 weeks ) or dehydrated.

i had that at the beginning of my pregnancy also till week 30-32 came to find out i have severe anemia and low blood count that's what caused me to feel like that you should ask your doctor i take iron pills 3 times a day now and feel much better.
