There is. I would go to the doc and get a blood test done.
2 false positives are very rare, It is possible to bleed/spot during the early stages of pregnancy but it's usually very light and pink/brown. Although it is possible to continue having periods as normal throughout pregnancy-rare but possible. I would advise you take another test and see what it says and go from there as false positives are rare...especially two...unless it was a chemical pregnancy?!?!! Good luck x
