Hi everyone, I am very stressed right now not knowing whether i am pregnant or not. I am 18 years old and I'm not to the point in my life that i want a child yet. I have a boyfriend, we had sex and used a condom. None of the times was there a sign of a rip or anything. My period came 1 week late this month, i didnt see any difference in blood flow or anything. A week after my period finished i am still experiencing a burning sensation at the top of my stomach, right under my ribs. and sometimes a sharp pain my lower abdomen on the left side. some times when i have a bowel i wipe and there is blood. Are these signs of pregnancy. PLEASE HELP.
