Negative at home pregnancy test show 7 weeks after intercourse? &if I were pregnant would I get my two expected periods? Because I did get my periods?!

Back to school. You do not need a physician to tell you that you are not pregnant. Having a period is your body's way of confirming that you are not pregnant. You wasted money on a pregnancy test given you have had your periods. You are not pregnant!
Double check. Ok, so i think you are saying that your pregnancy test is positive 7 weeks after last unprotected intercourse. I would recheck in a week. Alternatively, you can go to your doctor and get a blood test, which is more accurate. There are sometimes false positive results. Sometimes you can be pregnant and get bleeding, were the periods regular and 28-31 days in length?
