My period is 2 weeks late, the home pregnancy test came back negative, I keep having really bad lower abdominal pain i've been having hot flashes and then become freezing cold. I have a lot of clear liquid discharge. I just got married the 18th of september, and have been under some stress. I keep getting this odd cravings, but they change a lot. I'm vomitting after eating certain things and smelling certain things, and some scents of perfumes that I'm used to wearing have been really bothering me lately to where it makes me naucious. Is this just stress, or may I be pregnant. Again, I've taken multiple home preg. tests
