Hi, I'm a 20 year old female. For the past two months I haven't had a period at all. I've gained weight, I'm a little nauseous (no throwing up but I do taste bile), my breast look like they're swollen and I've been having headaches but everytime I take a urine test it comes up negative. I was on the nuvaring but I stopped in July and may and june I was late putting it in. I have been having unprotected sex with my fiancee. I've been trying to go to the doctor but it's been a little hard to work around my work schedule during the holidays. Is it possible that I'm pregnant and my hcg levels are just low or am i really sick? I just wanted some opinions.

I would suggest going to a doctor and getting an exam (gyenocologist). He/She will be able to tell if you are pregnant with more than a pregancy test.
