I had unprotected sex on 17 august.
Then I had my period from 3-7 September which is normal heavy flow.
On 18 september, I got brown discharge.
Then on 27,28 and 29september, I got red spotting (only for one time then change back to brown discharge).
My period was supposed to come on 8th october, but I missed it.I have breast tenderness and back pain.
I also took lot of pregnancy test before & after I miss my period. And all were negative.
What does this mean? Am I pregnant? Could it be that I took test too early?
I didn't have any sex after 17august.
