This is my second pregnancy I lost the first one at 9 weeks so I'm still new at this... I go tomorrow for my first ultra sound they say I'm only about 8 weeks but I think I'm farther along than that. today I have felt like I could not get enough food. I ate breakfast this morning and every since then I've felt hungry again every 15 mins is this normal. My mom said I need to be careful cause it could cause problems for the baby and also is it true that if i strech with my hands over my head that it could wrap the umbilical cord around its neck?
