Hi i am 23 years old and have 2 wonderful boys. The youngest being 1 1/2. I was having my period normally after i had him and for the last couple of months it was getting later and later in the month and now i havent had my period for 6 weeks and have all the pregnancy symptoms. they inlcude breast tenderness, hungry all the time. nauseous. some period like cramping. and o my last period only lasted 2 days. i went to the doctor two times already to gfet urine tests and both negative. I still feel pregnant. i dont know what to do. i dont know if its still to early or anything. Is it possible i could be pregnant. does anyone know? i feel like i have to throw up but i just yawn instead, i know that sounds a little weird. What are my chances.I have never missed a period since i started when i was 14. anyone please help me.
