Hi I'm 25 years old. My periods were due on 18th of this month. I had unsafe sex on 8th. Did HPT after 10 days till was negative. Again did it on 14th day still negative. I don't have any symptoms of pregrancy like swolen break, tiredness or any other. My periods were regaular for the past years. I've given urine test and waiting for result. What if its negative too then? Shld I wait for another week for my periods or what? Waiting for your answer. Thanks
