I have small cramping, like i would have with a period, but no lower
. I am extremely exhausted, and throw up in my mouth after every time I eat. I feel tighter across my stomach, and my nipples are extremely sore and the glands around them are raised, as well as I have been having to use the bathroom more. I have taken several hpts but they are all negative. I was wondering if I could be pregnant, and if I am, does my having taken plan b risk the baby having defects?
