I am trying to conceive... So I had unprotected sex December 4th.. so on the 15th I took a hpt it was nor negative or positive so I felt the test was invalid and I couldn't be but then.. On dec 17th I got very light bleeding.. it kept coming and going for two days straight I then thought I couldn't because of the bleeding.. but it's now dec 31 and since dec13th I've been having rising headaches always tired and very bloated and my partner has been feeling very sick but I haven't... so I don't know what it is I don't know if I should go to the doctors cause Idont want to waste there time and mines if it's nothing I just want to know has anyone ever experienced this before I just need advice thanks .

Simply put, you took the test too early. To get the most accurate response in is best to take the test with first morning urine when your period is two weeks late.
