Hi, may I answer your health queries right now ?  Please type your query here...  Hello there
Welcome to Chat Doctor .1. Your history suggest me there are possibilities to get pregnant.2. The practice of pulling out before ejaculation - is no at all a safe mode of contraceptive method, maximum possibilities of pregnancy.3. The symptoms you are mentioned are seen in the pregnancy.4. At the moment I would suggest getting a urine pregnancy test done to rule out the pregnancy.5. An ultrasound abdomen and pelvis will help to evaluate the cause of lump feel in the stomach area and confirm the pregnancy if there is one.6. If their is actually mass as you feel - scan will assess the type of scan and its extensions. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
