Hello its been 8 days since I missed my period an today when I went to the restroom when I used it it was a spot of blood when I wiped 2 hours later I use it an the blood is brown an only when I use the restroom what do this mean?

Could you be pregnant ? Are you having sex ?

If you are having sex, yes of course you could be pregnant, no birth control is 100 percent.

So at 8 days, you should be able to take a pregnancy test, get one ( they tell me clear blue is good, don't know from personal use (haha)) But use it first thing in the morning, first urine of the morning.
