I am 9 days missed period, no signs of a pregnancy and hpt came back negative
Many things can cause a late period. You can take a pregnancy test again in a week or so if you still do not have a period. You can also talk to your ob-gyn about it.
It is normal to have irregular periods. However if this is constant, go and have a check up to ensure that it isn't something serious to be on the safe side.
MIne is 13 days late since my last intercourse...
