Hi, I am 20 years old and I have missed my period for the past 4 month. I took a pregnancy test every month and they ve all turned out negative, my stomach has been really unbearable sore with cramps almost every night, I have been vomitting as well roughly 3 times for each past month. My breast have grown significantly large and sometimes my nipples hurt and at times they seem like they have been burnt abit. My urine has become darker and I pee quite a lot, when I walk my tummy hurts a lot. Your advise would be much apperciated. -Constance
