Hello, Im 18 and I been having a few symtoms I'm not sure if I am pregnant or not. I've been on birth control since July 2009 (Started with Depo shot, I recently got off of it September2011. Then Started Birthcontrol pills from then to April 2013) I finally stopped the medication for good. Had a period twin in April then my periods were back on track and going good til July I had two periods again! One in the beginning of the month then another two weeks later! I am sexually active with my boyfriend with no protection. We've had sex a few times in July and two weeks from the last time we did in (in July) (tested August 5th) my preg test was negative. I did not get a period in August. I stated spotting aug 31 brown and continued into September and lasted a few days. I bleed a little but not a normal period. I've been having mostly all the symtoms to being pregnant. Breast change, fatigue, nauseous in the morning even in the evenings, headaches, body/back aces, my veins show a lot more, my breast are tender with dark circles around them, I feel tugging sensations/ flutters on my lower abdominal area, tugging my by belly button, and tighting in lower abdominal, and weird bowel movements & bloated and gassy. Idk if I'm pregnant, if it's birthcontrol effects or stress? Even tho I don't think I'm stressed I probably am. I really need some help, sorry if it's TMI. I just need to know what this is.
