Is it possible for me to be pregnant

Can it be possible that I am pregnant and still get my period the reason why I ask because my period came on june 20th and before my period had came on I was feeling nausea in the morning and my breast were sore and had more headaches then usually so...

that made me think that I might be pregnant so I waited to see if my period would come on before I did a home pregnancy test and it did but my cramps was not as bad as they usually are and my period went off tuesday and still when I wake up it still feel like I have to throw up but never do and my breast are still sore in some spots so can somebody tell me whats wrong or what to do

we can not give you proven medical advice, but you might have an atopic pregnancy

MY COUSIN HAD A PERIOD 7 MONTHS OF HER PREGNANCY SO YOU COULD BE... KEEP ME INFORMED...
