Welcome to Gaia! ::

So ever since I started the pill, in 7th grade, I have had a normal and regular period. Coming every month exactly as planned until 2 months ago. I am now 19 and my last period was around august 25th.

My bf and last had sex around August 20th(we are now at college) but I was on the pill and he had a condom and I got my period on the 25th, and also for some reason my period stopped for a couple of hours then came back at it's usual flow. Around beginning of september I ran out of birth control and there were issues with refilling the perscription so I had to wait to take my pills after my last period.... but it hasn't come yet. It is now November and my period is nowhere to be seen. It FELT like I was about to get my period in september like usual but it never came instead some weird whitish/brownish gunk ball came out of my vag the size of a marble(gross I know sorry=/)

in september I lost about 15 lbs and changed my diet to not eating meat from our school's dining hall and c-store, it could be due to a diet change from all the awesome food from home to shitty college food(I am taking iron pills and vitamins and even though I am lacking a lot of protein I am trying to make up for it in supplements.)

So I don't really think I'm pregnant since I was on the pill until like early september and I had a period before then and last time I had sex was august 20th. Where is my period!? I've missed birth control before and still have had my period according to schedule!

Sorry for the long explanation... please help? Sorry if anything is unclear.
