I'm 7 days late for my period,I've been going toilet allot,I've had slight cramping without pain,I took 2 pregnancy test last week both came out negative. Now 3 days ago I had a brown stain in my knickers and on and off a brown discharge every time I go toilet but no bleeding or pain. I'm very confused so please if you can help I'll well appreciate it.:)

Since your tests were last week... maybe give it several more days... till this weekend perhaps, and try another test if your period still doesn't show up. It may just be late this cycle.
