So I had gotten my last period on December 12th and it ended on the 17th. Well now its January 25th and Ive taken 2 pregnancy tests and both were negative. I was on depo for over a year and had stopped about 8 or 9 months ago so my period is fairly normal. They have been around 28-32 days apart every month. Ive been feeling nauseous and weird lately. I went to the doctors and they think im not pregnant because the pregnancy tests were negative but than why have I not had my period? Just have been nervous about this and really need to know since Im only 16 years old.
