Hi, I'm 18 and sexually active. I've been off birthcontrol pills since April 2013 and had normal periods since then... Until July where I had two periods? Normal period was on July 1st -4th and two weeks later I had a really messy period that lasted a whole week. I've been having sex unprotected through out the whole month or July. And I missed my period in August I started spotting brown but only when I wiped and that continued into September and some blood came not a normal period tho. I hardly ever start my periods with brown discharge. Anyways since the middle of August ad the entire month of September I had pregnancy symptoms. Breast grown, tenderness, dark circles around nipple, fatigue, morning sickness, also flutters/tugging sensations in my lower abdomen also by belly button. Just a few days ago I didn't have any symptoms at all anymore(except headaches and flutters) and started spotting and not some mild bleeding. I feel nauseous and still feel flutters. Is there a possibility I'm pregnant? Or what Is going on????
