I found out today that I am not pregnant. I started my period and I have really bad cramps. I haven't felt this way sents I was a 11 years old. That is how old I was when I first started my period. I went to do the doctor then and they told my mom that I was just ovualting (hoped I spelled that right) and gave me some pain pills. But after that I haven't hurt that bad until now. I am alittle upset that I ain't pregnant. A little scared that something is wrong that is stopping me from getting pregnant. See one of my cousin had or has endometriosis and if I remember right the doctor's told her that it runs in the family. See my periods has never been normal like her wasn't. There was this one time that I went two monthes without a period. So I guess my question is is it possible that I could have endometriosis and is missed period or painful cramps symptoms of the endometriosis.
